Answer :

(a) Here Potential difference = 230 V


Current = 8A


Time = 1 Second


As we know that


The flow of electric charge per unit time is known as electric current.




So in each second the amount of charge flowing in the circuit is 8 C.


(b) As we know that the work done is equal to the amount of energy transferred in a circuit.


Electric potential difference is known as voltage, which is equal to the work done per unit charge to move the charge between two points against static electric field.


So,



So, Work done = 230 × 8 = 1840 J


It is also equal to the total energy transferred to the heater in each second
