Question

Initially the circuit is a steady state when the switch s is closed the heat generated in circuit

Answer 1

The charged on the capacitor during steady state is (20*4)=80 ... What is the energy stored in the circuit before the switch is closed?

Answer 2

Answer: The heat generated in the circuit is  ZERO.

Explanation:

when a switch is closed potential difference between capacitor is still E, therefore the heat cannot be generated and it would be 0
