Current
Current is the rate of transfer of charge
1 of 9
Coulomb
Coulomb is product of amp and second
2 of 9
Potential difference (p.d)
Energy lost, by charge flowing through a component, per unit charge.
3 of 9
Electromotive force (e.m.f)
Energy gained, by charge glowing through an electrical power source, per unit charge.
4 of 9
Terminal p.d.
The potential difference measured across the connections of battery or power supply. It is less than e.m.f. when a current is flowing due to the internal resistance.
5 of 9
Power
The rate of energy transfer
6 of 9
Kilowatt-hour
Is the energy transferred by a 1000Watt device running for one hour.
7 of 9
The ohm
The ohm is the resistance of a component when potential difference of 1 volt is produced per ampere of current.
8 of 9
Electric current
A net flow of charged particles.
