The correct answer is:
$1.08 \times 10^{4} \mathrm{~J}$
Given, $I=5 \mathrm{~A}, V=6 \mathrm{~V}, t=6 \mathrm{~min}=6 \times 60=360 \mathrm{~s}$
Heat produced in a circuit =Chemical energy reduced in the battery
$\Rightarrow$
$\begin{aligned}
H &=V I t \\
&=6 \times 5 \times 360 \\
&=10800=1.08 \times 10^{4} \mathrm{~J}
\end{aligned}$
