Physics - EMI/AC Question with Solution | TestHub

A coil of inductance$2 \mathrm{H}$having negligible resistance is connected to a source of supply whose voltage is given by$V=3t$volt. (where$t$is in second). If the voltage is applied when$t=0$, then the energy stored in the coil after$4 \mathrm{s}$in$\mathrm{J}$,
