What is the name of the store of energy in a battery?
All are good of electricity.
Most non metals are poor of electricity. A poor electrical conductor is called an .
Conductors allow electrons to flow through them easily. is a good conductor but it is expensive to use for wires so we use in electrical wires.
s do not allow electric current through them easily.
What is the unit for current?
If 50 joules of energy are used to move 5 coulombs of charge, what is the potential difference? (please include unit)
Calculate the potential difference when 30 joules is used to move 3 coulombs of charge. (please include unit)
We can calculate the current in a circuit by finding out how much charge (from electrons) flows past every second. We place it in the circuit like this:
The equation to find current is this:
Example: 10 coulombs of charge flows past in 2 seconds. What is current?
10 / 2 = 5 Amps
If a charge of 12 coulombs flows in 3 seconds, what is the current?
Calculate current from 15 coulombs over 5 seconds. What is the result?

This is the same diagram as above. What is wrong with it?
