Question

When a charged capacitor is disconnected from a battery and if its plates are separated further, then find the change in its potential energy.​

Answer 1

Answer:

if its plate are separated further, the potential energy will fall. <br> Reason : Energy stored in a capacitor is equal to the work done in charging it.

Answer 2

Explanation:

Charge stored on the capacitor remains the same if the battery is disconnected.

So, electric field between the plates remains the same.

Potential difference V=Ed

Thus, potential difference between the plates increases with increase in separation between the plates.
