Dear Student,
Work done in tranfering charge q across a potential difference, W=qVIf a current of I=2A flows in the circuit for t=2min=120sTotal charge transferred in the circuit, q=It=2×120=240 CPotential difference between the terminals of the circuits, V=3VThus,Total work done, W = qV=240×3=720J

Regards
