1. For t ≥ 0 the current through a 4300-μH inductor is iL(t) = 1e- 10,000t A. Find vL(t), pL(t), and wL(t) for t ≥ 0. Is the inductor absorbing power, delivering power, or both?
2. For t ≥ 0 the voltage across a 100-mH inductor is vL(t) = 15 e-100t V. Plot iL(t) versus time when iL(0) = 0 A.
(a) Solve using Multisim. In Multisim use the exponential voltage source, and set its initial value to 15 V and the pulsed value to 0 V.
Set the rise-time appropriately. Set the fall delay time well beyond the period over which you want to observe the response. Then, click on the inductor and set the inductor's initial condition to 0 A.
Plot the output using the transient analysis. Under "Analysis parameters," be sure to check the box under initial conditions to "User-defined" and set the "End time" to display at least five time constants.
(b) Solve using MATLAB.
