For the circuit and current waveform given in example 2 of lecture video 11, find the energy delivered by the source for all time.

Solution

Ws(t)=Wr(t)+WL(t)

eneregy lost in a resistor=i^2*R*t=1*i^2t=i^2t

energy stored in a inductor= (Li^2)/2=(i^2)/2.

energy delivered by the source=i^2t+(i^2)/2.
