Question

Two capacitors of capacitance 15 µF and 20 µF are connected in series to a 600 V d.c. supply. Find (i) charge on each capacitor, (ii) p.d. across each capacitor

Answer 1

(i) Equivalent capacitance, 

In series connection, charge on each capacitor is the same.

∴ Charge on each capacitor, q = CS V = (8.57 × 10^–6) x 600 = 5.14 x 10^–3 C

(ii) P.D. across 15 µF capacitor
