1
electricity
A form of energy caused by the movement of electrons.
2
charge
the electrons that are always in a wire
3
current
the flow of electrons in a wire
4
Voltage
The potential difference measured in volts. The amount of work to be done to move a charge from one point to another along an electric circuit.
5
electrical energy
this is carried by the current and is converted to heat and light energy in the bulb
6
The total current in to a junction should be equal to:
total current out of the junction
7
