Answer
$6.2\times10^{4}\,J$
Work Step by Step
$Energy=\frac{Energy}{Charge}\times Charge$
But $\frac{Energy}{Charge}=V$ and $Charge\,q=It=\frac{V}{R}t$
Therefore, $Energy= Vq=V\times\frac{V}{R}t=\frac{V^{2}\times t}{R}$
Substituting the values, we get
Energy delivered $=\frac{(120\,V)^{2}\times60\,s}{14\,\Omega}=6.2\times10^{4}\,J$
