The Charged capacitors are then disconnected from the line and reconnected with plates of same polarities together and no-external voltage. the charge on 3μF is

Three capacitors of capacitances 3μF,9μF and 18μF are connected in series across a 120V supply line. The Charged capacitors are then disconnected from the line and reconnected with plates of same polarities together and no-external voltage. the charge on 3μF is

Minimum number of capacitors of 4μF capacitance each required to obtain a capacitor of 10μF will be Three capacitors of capacitances 3μF
