Explanation:

My friend this is quite easy.

There is an equation.

The energy is also presumed as heat.

To calculate the heat in a circuit or the energy the equation is H=I (square) RT

Heat = square of current x resistance x time

Here I=5a.

R=2 ohm

T=120s

H = 5x5x2x120=6000J

I hope this satisfies you.
