Question

Find total energy stored in capacitors given in the circuit

Answer 1

C2 and C3 are in series

1/c' = (1/2) + (1/2) = 1

c' = 1μf

c' & C4 are in II

C = 1 +1 = 2μf

C & c5 are in series

1/c' = (1/2) + (1/2)

c' = 1μf

c' & c1 are in II

Ceq = 1 + 1 = 2μf

Energy stored

U = (1/2) cv2 = (1/2) x 2 x 10 - 6 x 62

= 36 x 10 - 6 J
