alleryStart learning →A charged capacitor is connected to an uncharged identical one. What happens to the total stored energy?
AIt doubles
BIt is unchanged
CIt halves
DIt becomes zero
Answer & Solution
Correct answer: C. It halves
Charge is conserved and shared equally, so total energy Q^2/(4C) is half the original Q^2/(2C), the rest being lost as heat.
