1
Q
Potential difference
A
The work done per unit positive charge
2
Q
Current
A
The rate of flow of positive charge
3
Q
Ohms law
A
Current through a conductor of is directly proportional to the difference across the conductor at a constant temperature

Q
Resistance
A
And materials opposition to the flow of electric current
5
Q
Electrical power
A
Power dissipated in a device is equal to the product of the potential difference across the device and current to flow through it
