Assume the line-to-neutral voltage in the 60 Hz circuit of

Chapter 13, Problem 13.92

(choose chapter or problem)

Assume the line-to-neutral voltage in the 60 Hz circuit of Fig. 13.59 is 120 l0 V (rms). Load is absorbing 1200 W; load is absorbing 1800 W; and load is absorbing 350 magnetizing VAR. The inductive reactance of the line (X1) is 1 k Assume Vg does not change after the switch opens. a) Calculate the initial value of and i (t). 2(tb) Find and using the s-domain circuit of Fig. 13.60. c) Test the steady-state component of using phasor domain analysis. d) Using a computer program of your choice, plot v vs. t for 0 t 20 ms.
