Why Does a Capacitor's Charge Remain the Same When Voltage is Removed?

[Rohan R T]

When voltage supply is removed from a parallel plate capacitor, why does the charge remain as before?

 

[Drakkith]

Because the charge has nowhere to go. It can't get through the dielectric, and there's no other path to the other plate.

why does the charge remain as before?

to be a little more specific
The charge on a capacitor never changes, that is, the net charge always = 0

You should get used to using the more correct term of the capacitor being energised
when an external voltage source is applied across the capacitor terminals
