Answer:

C

Step-by-step explanation:

From the formula

Q = CV

Where the V = voltage across a parallel plate capacitor

Q = charge

If V is doubled, automatically charge Q will also be doubled.

From the energy formula.

E = 1/2 CV^2

If voltage V is doubled, energy E will be squadripple.

Electric field strength E = V/d

If V is doubled E is also double.

Therefore, Doubling the voltage across a parallel plate capacitor does not double which of the following?

WhIch is the energy stored
