200
Why does your hair stand on end when you rub a balloon on it?
All negative charges so they repel eachother
200
Name two problems with using wind power

attract
300
What is electrical discharge
The spark that is created when electrical charges try to get to ground
300

Do we use mostly renewable resources for our power in Saskatchewan? What do we mostly use?
No we use coal or burning fossil fuels
500
Why do lights turn on so quickly if electrons move quite slowly?
Because all electrons are negative in charge they repel eachother to move. If one moves they all move.
500
What does a resistor do
Slows down the electrons and forces them to give off light or heat
