A parallel plate capacitor consists of two square parallel plates separated by a distance d. the potential across the plates, while keeping everything else constant, what happens to the energy stored in the capacitor? A) There will be % of the energy stored
B) There will be % of the energy stored
C) The energy stored will remain constant
D) The energy stored will double
E) the energy stored will quadruple

E) the energy stored will quadrupled

Explanation:

The correct question is

A parallel plate capacitor consists of two square parallel plates separated by a distance d. If i double the potential across the plates, while keeping everything else constant, what happens to the energy stored in the capacitor?

A) There will be 1/4 of the energy stored

B) There will be 1/2 of the energy stored

C) The energy stored will remain constant

D) The energy stored will double

E) the energy stored will quadruple

The initial energy stored in the capacitor =

where C is the capacitance

V is the potential difference

If I double this voltage, while holding every other parameters constant, the new energy stored will be

= =

=

dividing new energy stored by the initial energy stored, we have

= ÷ = 4

the energy stored will be quadrupled.

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .

yup its correct its: c) b b
