a) State the relation between potential difference, work done, and charge moved. b) Calculate the work done in moving a charge of 4 Coulomb from a point at 220 Volts to another point at 230 Volt.

Answer:

a) The relation between potential difference, work done, and charge moved:  Potential difference = (Work done)/(Charge moved)

b) Given information in question:

V1 = 220V

V2 = 230V

Charge moved = 4C

To find, Potential difference = ?

We know that potential difference is:

Potential difference = V2 – V1

= 230 – 220 = 10

Work done = Potential difference × charge moved

= 10 × 4 = 40J

Therefore, the work done is 40J to move charges.
