Question

Why do we need a capacitor to store energy when we already have a battery to do that?



Your Answer
A

It is because a capacitor can store a very-very large amount of energy

Your Answer
B

It is because a capacitor can provide the stored energy back relatively slowly

Correct Answer
C

It is because a capacitor can provide the stored energy back relatively quickly.

Your Answer
D

It is because batteries are obsolete


Solution

The correct option is C

It is because a capacitor can provide the stored energy back relatively quickly.


A capacitor is used to store energy just like a battery. But a battery has energy stored in form of chemical energy and a capacitor has the energy stored as electrical energy. So, a capacitor can provide energy really quickly compared to a battery.
