Q.88. The heat generated in the circuit after closing the switch is
(1)
(2)
(3) 2
(4) Zero
dear student
initial potential energy of the capacitor = 1/2 CV2
finally the negative plate of capacitor become positive charge
initial charge on capacitor plate= q=-CV
final charge=q=+CV total charge flown = 2q=2CV \
work done by battery= q(V) where q= total charge flown through battery
so W= 2CV*V= 2CV2
as there is no change in the energy of capacitor so the total work done by battery is released in the form of heat energy
initial potential energy of the capacitor = 1/2 CV2
finally the negative plate of capacitor become positive charge
initial charge on capacitor plate= q=-CV
final charge=q=+CV total charge flown = 2q=2CV \
