Problem 5: iin (1)For the circuit given iin = lo cos wt with I. > 0 R a) Write expression for the complex impedence Z as seen by by the current source. b) Write simplest expression for Z in rectangular L form in terms of R, L, and w. c) Give the simplest expression for the phasor for voltage drop downwards in cartesian form in terms of R, L, w and lo. 0000W d) Give the expressions for Real, Apparant, and Complex power delivered to the RL branch (P, Q, and S, respectively)in terms of R, L,w. rad NOW Let w = 5000, L = 20 mH, R = 100 1. Find Z,P,Q,S and the S power factor. Give units. Also find the voltage drop across RL in phasor domain and in time domain.

(II) We modify the circuit by putting a shunt capacitance C = 2 uF = (a) Calculate Z as seen by the current source R (in rectangular and polar form) (ab) Find the Voltage supplied by the Current source in terms of 16. (rectangular and phasor lin form, as well as in time domain) С 0000-WW HE L Give new values and units for ,P,Q,S and the power factor for the new circuit.
