✼ ҉ ҉ ҉ Introduction ҉ ҉ ҉ ✼
Hi Bloggers!
This term week 5 we were learning all about electricity and how it works. We learnt about electrons (negatively charged and positively charged electrons) and how neutrons work and what they do. One fact I that learn’t was that negatively charged electrons and positively charged electrons attract each other, and on the other hand a positive electron to a positive electron, and a negative electron to a negative electron repel each other.
✼ ҉ ҉ ҉ The Electron Journey ҉ ҉ ҉ ✼
I was an electron, happily attached to my balloon. Suddenly the balloon was rubbed against a jumper. As it moved back and forth I was pulled away from the balloon and onto the jumper.
At first it felt strange. I was now stuck on the jumper with lots of electrons. We were all crowded together and the rubbing that happened the more electrons joined us. This was called buildup. I could feel the tension growing because there were many electrons in one place.
Then suddenly I saw a conductor nearby. I felt a pull towards it. In an instant I jumped from the jumper to the conductor! Other electrons moved too spreading out the charge and balancing everything again.
What a journey! I had gone from being on the balloon to being stuck on a jumper and finally making a tiny electric jump, to the conductor.

Circuit
─── (
) ─── /// ─── (A) ───
│______________________________│
Power supply: Gives energy to the circuit.
Lightbulb: Changes energy into light and heat.
Resistor: Reduces the current.
Rheostat: Changes the resistance.
Ammeter: Measures current.
Voltage and Current
If voltage goes up and resistance stays the same current goes up too.
Where does the energy go?
The light bulb changes energy into light and heat.
