Problem 13: Three capacitors of capacitances 4 µF, 6 µF and 8 µF respectively are connected in series to a 250 V d.c supply. Find (1) the total capacitance (2) charge on each capacitor (3) P D across each capacitor.
Easy. Try yourself.
For equivalent capacitance use formula
Charge on each capacitor will be the same. Calculate it using Q = CeV
For potential drop use formula
