Homework 31 ECE201: Linear Circuit Analysis Due in class: Monday, November 14, 2011 Question 1 The circuit showing in the following figure operates in the sinusoidal steady state with the indicated phasor currents with is(t) = 10 cos(1000t) A. Find the value of the phasor currents and the associated i1(t) and i2(t). !Question 2 Use KVL to determine the phasor voltage Vx in the circuit below.!Question 3 For the circuits in the following figure, compute the indicated phasor currents assuming R = 2 ! and L = 4 mH, and C = 1 mF. If " = 500 rad/sec, determine the associated time function. !Question 4 Find the phasor currents IR, IC, IL, and Iin, and then determine iin(t) for the circuit of the following figure in which R = 1 k!, L = 0.5 H, C = 1 µF, and vin(t) = 20 cos (1000t + 60°) V.
