Write three different formulas for the energy stored in a capacitor.
(N/A) The energy stored $(U)$ in a capacitor with capacitance $C$,charge $Q$,and potential difference $V$ is given by the following three formulas:
$1$. $U = \frac{1}{2} CV^2$
$2$. $U = \frac{Q^2}{2C}$
$3$. $U = \frac{1}{2} QV$
These formulas are derived using the relationship $Q = CV$.
$1$. $U = \frac{1}{2} CV^2$
$2$. $U = \frac{Q^2}{2C}$
$3$. $U = \frac{1}{2} QV$
These formulas are derived using the relationship $Q = CV$.
