If you use the sheets at the back, indicate this clearly on the question sheet. Write your name and student number on the first page of the the exam as soon as you receive it. Write your initials and students number on each subsequent sheet. Return all the sheets of your exam stapled. Given that vs = vm cos( t), calculate the magnitude of the current in the capacitor in the following circuit : Derive the th venin equivalent of the following circuit. I(t) = 10 cos(10000t); r1 = r2 = 100 ohm; c = 1 m f; and l = 0. 01 h. In the circuit shown below, calculate e, ir, and il in phasor form. The following circuit has been in steady state before the switch opens at t = 0.
