(A) Given:$I = 2\, A$$t = 6\, 	ext{minutes} = 6 	imes 60 = 360\, s$$W = 1000\, J$We know that the work done $W$ in a circuit is given by $W = V 	imes I 	imes t$, where $V$ is the $e.m.f.$ of the source.Rearranging the formula to solve for $V$:$V = \frac{W}{I 	imes t}$Substituting the given values:$V = \frac{1000}{2 	imes 360}$$V = \frac{1000}{720}$$V \approx 1.38\, V$Therefore, the $e.m.f.$ of the source is $1.38\, V$.

For driving a current of $2\, A$ for $6$ minutes in a circuit, $1000\, J$ of work is to be done. The $e.m.f.$ of the source in the circuit is ................ $V$.
