Question

explain P.D potential.​

Answer 1

Ohm's law states that the current through a conductor between two points is directly proportional to the potential difference or voltage across the two points. Potential difference is the work done in moving a unit of positive electric charge from one point to another.

Answer 2

Potential difference. When resistors are connected in series, the total of all the potential differences (sometimes referred to simply as voltage) around the circuit is equal to the potential difference (p.d.) of the supply: ... The supply voltage is a measure of the energy supplied to each electron. The p.d.
