Question

If the potential
difference across a capacitor is doubled, what happens
to the energy stored?

A
It becomes two times larger.
B
It becomes four times larger.
C
It is unchanged.
D
It becomes one-half as large.
E
It becomes one-forth as large.
Solution
Verified by Toppr

Correct option is A. It becomes four times larger.
Because $$U_E=\dfrac{1}{2}C(\Delta V)^2$$.
