   (a) State the relation between potential difference, work done and charge moved. (b) Calculate the work done in moving a charge of 4 C from a point at 220 V to and point at 230 V.

Answer:

                  (a) The relation between potential difference, work done and charge moved is given by Potential difference (1) (b) Given. Charge (Q) = 4 C, Potential at point APotential at point Work done Potential difference, Work done                         (2)
