The separation between the plates of a p...

The separation between the plates of a parallel plate capacitor is t, and the intervening space is filled with glass, of dielectric constant 6. Now, the separation between the plates is increased by t. How would the charge on the capacitor and the potential difference between its plates charge, if
The battery is disconnected before increasing the separation between the plates?

Text Solution

Verified by Experts

No change of charge, potential difference will be 7 times
