Question

When two capacitors are charged to different potentials and then connected in parallel to each other, then :-

Options

A.Final charge is equal to sum of initial charges

B.Final potential difference is equal to average of the initial potential difference

C.Final potential difference is different from the sum of initial potential difference

D.final energy stored is less then the sum of initial stored energy

Solution

C₁V + C₂V = C₁V₁ + C₂V₂ (charge conservation)
V =
Heat = U₁ - U₂
= (C₁ + C₂)V²
