Q38. The capacities of two capacitors are C₁ and C₂ and their respective potentials are V₁ and V₂. If they are connected with a wire, then the loss of energy is given by:
(a) C1C2(V1+V2) / (2(C1+C2))
(b) C1C2(V1-V2) / (2(C1+C2))
(c) C1C2(V1-V2)² / (2(C1+C2))
(d) (C1+C2)(V1-V2) / (C1C2)

Question

Accepted Answer
