Three capacitors each of capaitance 9pF ...

Three capacitors each of capaitance 9pF are connected in series.
(a) What is the total capacitance of the combination ?
(b) What is the potential difference across each capacitor if the combination is connected to a 120 V supply ?

Text Solution

Verified by Experts

Resultant capacitance in series combination `(1)/(C_5)=(1)/(C_1)+(1)/(C_2)+(1)/(C_3)rArr (1)/(C_S)=(1)/(9)+(1)/(9)+(1)/(9)=(3)/(9)=(1)/(3),C_S=3pF`.
