Step 1

From the graph vL(t) is linear from vL(−1)=+10 V to vL(1)=−10 V, so for −1 ≤ t ≤ 1 vL(t) = −10 t. (For completeness, for 1 ≤ t ≤ 3 the line is vL(t)=5t−15, and vL(t)=0 for t<−1.) Show more…

For the circuit shown above, the voltage v(t) across the 3 H inductor is VL(1) = 3H. If VL(t) is shown, then the inductor current at t=1 second, iL1, is.
