Problem

A laboratory has an unlimited stock of identical capacitors, each of capacitance

4\,\mu\text{F}

. A capacitor bank of

96\,\mu\text{F}

is to be assembled using only parallel connections. (i) Calculate the minimum number of these

4\,\mu\text{F}

capacitors required. (ii) If the completed bank is connected to a

50\,\text{V}

power supply, determine: (1) the charge on each individual capacitor, (2) the total electrostatic energy stored in the bank.
