Calculate the electric potential energy in a capacitor that stores 4.0 x 10-10 C

ioda

The electric potential energy is $1\cdot 10^{-7} J$

Explanation:

The electric potential energy stored in a capacitor is given by the equation

$PE=Q \Delta V$

where

Q is the charge stored in the capacitor

$\Delta V$ is the potential difference between the plates

For the capacitor in this problem, we have

$Q=4.0\cdot 10^{-10}C$ is the charge

$\Delta V=250.0 V$ is the potential difference

Substituting, we find the potential energy:

$PE=(4.0\cdot 10^{-10})(250.0)=1\cdot 10^{-7} J$
