Document Summary
No aids other than the approved calculators are allowed: all questions are of equal value. If doubt exists as to the interpretation of any question, the student is urged to submit with the answer paper, a clear statement of any assumptions made. In the circuit shown below, the current through the inductor, i(t), is governed by the following equation: i(t) = 3 + 2e-3t a for t 0. Q2: the following circuit is at steady state before the switch closes at time t=0. Determine the capacitor voltage, v(t), for t 0. Q3: determine the voltage va(t) for the following circuit when is(t) = 20 cos ( t+53. 13 )a and = 104 rad/s. Find the thevenin equivalent circuit between point a and b for the following circuit: Find the complex power delivered by the voltage source and the power factor seen by the voltage source for the following source:
