When a potential difference, V is applied across the ends of a resistor of resistance, R a Current, l passes through the resistor. The heat generated in the resistor in time, t is given by the expression

We were given
V, I AND R.
They said a voltage is applied accross the ends of a resistor and current passes through, so we should kno that power would be dissipated.
Power dissipated = I^2r
and power = energy / time
energy = power x time
so, energy = i^2rt
