find the potential difference between th point A and B and between the point B and C of figure in steady state.

Explanation

`C_eq = [(3muf P 3muf ) S ( 1 mu f P 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 f capacitors
` = 100 mu c `
Charge flowing from A to B
` = 150 mu c = Q `
` Ceq between a and b is 6 mu f = C `
` potential drop across AB = V `
` Q/C = 25 V `
` Potential drop across BC = 75 V. `
