Answer» Solution :`C_eq = [(3muf P 3muf ) S ( 1 mu fP 1 mu f ) (P mu f) ` ` [ S = SERIES , P= parallel ] ` ` = [(3 + 3 ) mu f S (2 mu f)] P 1 muf ` ` = 3/2 + 1 = 5/2 mu f ` ` V = 100 V ` `Q = CV = 5/2 xx 100 = 250 mu C . ` Charge stored across 1 mu fcapacitors ` = 100 mu c ` Charge flowing from A to B ` = 150 mu c = Q ` ` Ceq betweena and b is 6 mu f = C ` ` potential drop across AB = V ` ` Q/C = 25 V ` ` Potential drop across BC = 75 V. ` |
