Two capacitors C₁ and C₂ each of area 36cm² separated by 4cm have capacitances of 6µC and 8µC respectively. The capacitor C₁ is charged to a potential difference of 110V where as the capacitor C₂ is charged to a potential difference of 140V. The capacitors are now joined with plates of like charges connected together.
