Question

A capacitor has some dielectric between its plates and the capacitor is connected to DC source. The battery is now disconnected and then the dielectric is removed then.

1.capacitance will increase
2.energy stored will decrease
3.electric field when increase
4.voltage will decrease ​

Answer 1

Answer:

Solution :

When the capacitance is connected to dc source, it gets charged. The battery is now disconnected So no more charge can flow in, i.e., charged stored will stay constant. On removing dielectric, capacitance decreases . <br> Energy stored

will increase, Pot,

would increase

will increase.
