W 2000 Problem 5: (1)For the circuit given in = 1, cos ut with I, > 0 a) Write expression for the complex impedence R Z as seen by by the current source. in 1 b) Write simplest expression for 2 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 Io. 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. NOW Let w = 5000L = 20 mH, R = 100 . Find Z.P.Q.S and the power factor. Give units. Also find the voltage drop across RL in phasor domain and in time domain. rad (II) We modify the circuit by putting a shunt capacitance C = 2 °F (a) Calculate Z as seen by the current source (in rectangular and polar form) R (ab) Find the Voltage supplied by the Current source in terms of lo(rectangular and phasor in form, as well as in time domain) L Give new values and units for, P. Q.S and the power factor for the new circuit. с W 2000- HE
