Homework Statement


Circuit diagram of capacitors labeled 6 μF, 4 μF, 8 μF, 9 μF, 9 μF, 7 μF and 36 μF connected across a 40 V source, with multiple-choice options listed below.


Homework Equations

The Attempt at a Solution



Apologies for the question image not being very clear . I will refer capacitors by numerical value of their capacitance .

The 6 , 4 , 8 capacitors are in parallel .

9 , 9 , 7 are shorted out .So , we can remove them from the circuit .

So , effectively , the equivalent of 6,4,8 is in series with the 36 capacitor .

One end of 6,4,8 is at 40 Volts .Other end I calculated to be at 40/3 volts.

From this I get potential difference across 8μf capacitor to be 80/3 volts and charge 640/3 μC .

I get Option 3) .

Is this correct ?
