Question 14: Explain why capacitors are of little use for the storing of energy for normal domestic purposes of lightning, heating and so on.

ANSWER

Capacitors are of little use for the storage of energy for normal domestic use due to the break down phenomenon of the capacitors. The capacitors can hold a certain charge depending upon its capacitance. Increasing more charges makes them jump from one plate to another through the dielectric and the capacitor starts discharging. Therefore, more energy cannot be saved as the energy stored depends upon the charge held by the capacitor.
