1.      (30 points)

a.   Calculate the value of rms current, Irms, flowing through zL.

b.   Calculate the complex power, S, for zL. Include appropriate units.

 

ans:  a)     Irms = 10 Arms

         b)     S = 100 + j400 VA

 

sol'n:  (a)   The circuit is a current divider:

 

sol'n:  (b) 

S = 100 + j400 VA
