Question

14. (a) State the relation between potential difference, work done and charge moved.
(b) Calculate the work done in moving a charge of 4 coulombs from a point at 220 volts to another point at
230 volts.
to measure the potential difference across a conductor.
which it moves​

Answer 1

a)The potential difference between two points in an electric field is defined as amount of work done in moving a unit charge from one point to other point. Potential difference = Work Done/ Quantity of Charge moved.

b)So, the work done in moving a charge of 4 coulombs from a point at 220 volts to another point at 230 volts is 40 Joule
