In this circuit 1 mu F capacitor stores 100x mu C charges Wh

In this circuit, 1 mu F capacitor stores 100x mu C charges. What supply voltage between a & b?

Solution

Here,

for the net capacitance between a and b

1/Cab = 1/(1 + 3 ) + 1/4 + 1/12

Cab = 1.714 uF

Now , let the voltage across the point a and b is V

charge on 1 uF

100 * 2 = V * 1.714 * 1/(1 + 3)

solving for V

V = 467 V

the potential across the point a and b is 467 V
