Ohms (Ω) in Series and Parallel Circuits

Ω is the symbol for the ohm — the unit of resistance, meaning how much a component opposes the flow of electric current. More ohms = harder for current to flow.

Series Circuits

Resistances add up:

Rtotal=R1+R2+R3+…R_{total} = something 

Meaning: because there’s only one path, the current is forced through every resistor one after another — so the resistances stack up, making it harder overall.

  • Current is the same everywhere: I = I1 = I2 = I3
    Meaning: with only one path, the flow can’t split — the same amount of current passes through each component.
  • Voltage is shared between components (adds up to the supply voltage)
    Meaning: the battery’s energy gets divided up across the resistors.

Example: Two 4 Ω resistors in series →​4+4=8 Ω (double the path, double the difficulty)

Parallel Circuits

Resistances combine using reciprocals:

1Rtotal=1/R1+1/R2+1/R3+…

Meaning: each branch gives the current an extra route, so the overall path gets easier — even though every resistor still has its own resistance.

  • Voltage is the same across each branch
    Meaning: each branch connects directly across the battery, so every component gets the full push.
  • Current splits between branches: I total​=I1​+I2​+I3​
    Meaning: the total flow entering the circuit divides among the paths, then rejoins.

Example: Two 4 Ω resistors in parallel →Rtotal​1​=4/1​+4/1​=2/1​, so Rtotal = 2 Ω (two equal paths = half the difficulty)

Key Points to Remember

  • Parallel resistance is always less than the smallest individual resistor — more paths always makes flow easier

 

  • Series resistance is always more than the largest individual resistor — stacking resistors always makes flow harder

 

  • Ohm’s Law: V= I×R, so I=VRI = I = RV​
    Meaning: the current you get equals the voltage (push) divided by the resistance 
  • (push-back) — bigger push or less resistance means more current.

Worked Example

A 12 V battery with two 4 Ω resistors:

  • Series: I =12/8 = 1.5A –  the doubled resistance holds the current to 1.5 amps through everything

 

  • Parallel: I =12/2 = 6 A total — the halved resistance lets 6 amps flow, splitting into 3 A through each branch

Ω (ohm) = the unit of resistance — how much a component opposes electric current. In circuits, the ohm is what determines how much current the battery can push through. The relationship between the resistances (in Ω) and the current (in amps) is what series and parallel rules are really about.

well we didn’t actually learn this yet well I did we have been learning about the circuit of a parallel and series and we haven’t learned this yet but maybe next time.

Is water Important?

Without water on earth the world would not exist and water is important because all the living things needs water to water for example animals and plants needs water to survive that they can be hydrated and humans need water to our bodies and skin hydrated and healthy without the water our plants will die and the animals won’t able to survive without water and humans they will be ill and sickness from being dehydrated and your skin can be dried and scaly. In my opinion water is keeping me hydrated, healthy, and feeling good. If I don’t, I get dehydrated, which is why this is important in life. 

 

Water has a lot of positive things that are good with water. For example you can drink freshwater, you can swim with the water, seawater, freshwater, the water cycle and the creek those are the things that we can use from water and the rain it feeds the plants, it fills, up the water tanks fast and healthy, filling up with the spring water, mountain valley spring water,  and filling up animals water feeding bowls and in my opinion water can be important for the plants and animals that they can survive from water. 

 

And the important thing is that we have to keep careful with the other water. Because the other can be dangerous for example there is polluted water, ground level ozone that is part of polluted water, dirty water, and the worst things of all time is the floods. Floods are a very dangerous water of all time because it can flood the roads that trap people’s homes and farmers. There, it overflows the plants and grass and it can trap the animals if they make it out and the smell is not good at all. And that is why we keep our positive water away from the negative water and in my opinion is that keep yourself safe the negative water away from us because it can make us ill, sick, sickness, and throwing up and that is why we keep away from the negative water and it’s important that we keep yourself safe. 

and we have been learning this in social studies thanks to Whaea Honey

well have a wonderful day today

Soccer kicking task

Last week 10k and I played a game to gather up some data to make a graph. This game is about soccer, you have to kick the ball 15 times to get some data. The graph has a range of numbers lowest-highest, the first graph the median turned out to be 4, and the second graph we added boxes and whiskers, the results came out and the median was 9.

This is a little math game, basically teaching you the data base of soccer. This is a graph that shows the calculations of how many times the ball has been kicked, this shows that the ball was kicked at least 15 times. I added the whisker boxes and used the median, range and the many others to help me find the data.

Climate Change Consequences

  • What is climate change?

Climate changes are the changes and shifts happening in the Earth’s climate over a long period of time. Averaging weather patterns and graphs in one specific place to measure climate change.

  • What is causing climate change?

As of now, the main culprit for the causes of climate change would be humanity. Releasing a substantial amount of carbon dioxide in the atmosphere for decades (approximately 60 years) to use for our agriculture, transportation, and electricity sources. The energy to power these sources and releasing carbon dioxide into the climate comes from greenhouse gasses, burning fossil fuels and nonrenewable energy, which have caused combustion in the atmosphere creating severe weather shifts and climate changes.

However, before human activities, carbon dioxide and heavy soot could be found from the eruptions of volcanoes. Causing similar weather events to Earth. The key difference is that the volcanoes are natural, doing it at a steady pace to help Earth’s atmosphere and allow infrared radiation and keep temperatures stable, but humans are proceeding this process way too fast and an unsteady rate from the amount of greenhouse gasses released into the atmosphere.

Greenhouse gasses include carbon dioxide, methane – cow fart, nitrous oxide, and water vapor. All contributing to rising global temperatures and extreme weather events. This happens from human activities that go through the process of combustion, releasing carbon dioxide and water vapor into the atmosphere, such as burning coal/nonrenewable energy, and causing the sun’s heat to get trapped and have the Earth’s temperature rapidly rise. Although, some greenhouse gasses are natural and needed to keep temperatures on earth warm and have the ability to grow crops. The natural greenhouse gas is water vapor, but when combined with carbon dioxide, methane, and nitrous oxide, it causes the atmosphere to be filled with dangerous gasses and rise in temperature, as they trap infrared radiation from Earth’s surface.

The greenhouse gases will then cause extreme weather events as the sun’s radiation will not have anywhere to bounce off if the atmosphere is weakening, and rely on the white ice caps. This creates a chain of events as ice caps rises, more moisture is released into the air, sea level rises, more rain, wind, and storms are up in our clouds, and affect humanity and cause disasterous weather events, therefore, climate change.

  • In 2019, the “school strike 4 climate” movement started in Aotearoa. It’s still continuing today. Why do ākonga (students) throughout Aotearoa and globally want to go on strike from school and protest?

Many students across the globe have chosen to strike and protest as a way for policies/systems and constitutions to change in order to protect the earth. From a continuation of burning fossil fuels, greenhouse gasses, and mass production of agriculture and instead switch to renewable energy sources and declare a climate emergency, regerative economies and go against environmental destruction.

Having students go out and protest instead of being at school would send a very strong message to the political leaders of today. As Greta Thunberg stated, “This is all wrong. I shouldn’t be up here. I should be back in school on the other side of the ocean. Yet you all come to us young people for hope. How dare you!”. It shows how there isn’t any point in going to school to study in future, if there is no hope for a future. Young audiences sacrifice learning time just for the leaders of today and hope something is done to prevent further weather destruction, habitat loss, global rising temperatures and extinction, so that the children of today can live in a proper environment that they are inevitably forced to inherit.

  1. What is climate change and how do we know its happening (hint: relate to keeling curve/graph activity)?

Climate change is the long-term differences in the global temperatues and weather-patterns. They are primarily from human activities like burning fossil fuels like coal, oil, and gas. When we burn these fuels they release greenhouse gases like carbon dioxide and these gases wrap around the planet like a blanket which makes the Earths heat trapped and making the global temperatures rise. A quote showing how dangerous this is for us and the Earth: “We are smothering the planet with greenhouse gases from the burning of fossil fuels, creating a blanket around the Earth that traps heat and forces global temperatures to rise. It is our activities—our destruction of the natural world—that have caused this crisis.” – Dr Jane Goodall. We know that climate change is happening because of scientific evidence using a graph called the Keeling Curve. The Keeling Curve is a long-term graph where it tracks the concentration of carbon dioxide in Earths atmosphere.

2. What is causing climate change? (150 words)

Climate change is mainly caused from human activities that that release greenhouse gases into the atmosphere, the greenhouse gases that normally release from these human activties are carbon dioxide, methane and more. The primary cause of climate change is burning fossil fuels, fossil fuels are coal, oil, and natural gas. Humans burn fossil fuels for transport, industry, and energy. In complete combustion it reacts carbon in the fossil fuels with oxygen to make more carbon dioxide and incomplete combustion means releasing soot and carbon monoxide. These gases can make the greenhouse effects more intense. Earth would reflect back solar heat into space but because of the greenhouse gases Earth gets hotter as the greenhouse gases act as a blanket which warms the blanket. Other things that cause climate changes are Deforestation which is cutting down forests and trees which release  the stored carbon dioxide. It also takes away trees that absorb CO2 from the atmosphere, Agriculture and Livestock with Cows and sheep in where they make huge amounts of methane when their digesting and release greenhouse gases.

3. In 2019, the “school strike 4 climate” movement started in Aotearoa. It’s still continuing today. Why do ākonga (students) throughout Aotearoa and globally want to go on strike from school and protest? (~150 – 200 words

Students around Aoteroa globally strike because they realize that the climate change that is happening to their planet threatens their future and they realise they need to intervine and do something about it. Students see the consequences at first in Aoetearoa, they see the intense floods, prolonged droughts, huge coastal erosion. Student around Aoteroa and around the globe see the rising temperatures and the sea levels rising, they also see the ecosystem collapse and seeing all these signs the students in Aoeteroa and the globe this is the reason why the students decide to go on strike. The movement or protest primary or most important demand is to stop the fossil fuel exploration. They want to invest a lot into renewable energy and lowering the emissions and keep the warming to stay at 1.5 C. The students want to protest for a fair shift to be more sustainable and have more sustainable economies wants to make sure workers that work in the carbon invested industries are not left beind. In conclusion the students decide to strike because they think missing a day of school is a needed sacrifice to have a planet where they can live in.

Explain how a character was or was not a positive role model for teenagers:

Explain how a character was or was not a positive role model for teenagers:

______________________________________________________________

 

In the novel “Lord Of The Flies” created by Willam Golding, Piggy stands out as the most positive role model for teenagers, while in the novel Piggy shows he’s a snitch but this is probably to his way of thinking about things he knows when things are right or wrong and that’s a great reason why he’s a positive role model and also  he’s a great role model due to him being intelligent, kind, and non violent. Piggy also shows that he is not as tempted to fit in and be a follower to higher social people like Jack, for example when Jack started hunting and made another group Piggy chose to stay loyal to Ralph and be one of his closest companions in time of need.

MATH create task!!!!!!!

Hey guys! I am Joey

today I am going to share my Maths create task!! it’s about centimeters and Meters

for example: 91 centimeters = 0.91 meters! so it means that adding a 0 in front of the 91 centimeters equals 0.91 m!!! do you understand now?

I am pretty proud of myself  because I usually do ESOL class by this time. (which means English class because my English is not really good) so I don’t really do math classes!
