Three capacitors, 1 pF, 2 µF and 3 µF, are connected in parallel across a 10 V d.c. supply. What will be (a) the total capacitance, (b) the resulting charge on each capacitor, (c) the resulting potential difference across each capacitor?

Three capacitors, 20 pF, 30 µF and 60
µF, are connected in series across a 36 V d.c. supply. What will be (a) the total equivalent capacitance, (b) the charge on the plates of each capacitor and (c) the potential differences across each capacitor?
