A practical voltage source is modeled by an ideal voltage source V with an open-circuited effective value of 320 V in series with an output impedance Z, = 50+j100 2. The source feeds a load Z = 200 +j100 2. See Fig. 10-30. (a) Find the average power and reactive power delivered by g. (b) Find the average power and reactive power absorbed by the load. (c) A reactive element jX is added in parallel to Ze. Find the X such that power delivered to Z, is maximized. Ans. (a) P, = 250 W and Q, = 200 var, (b) P = 200 W and Q = 100 var, (c) X = -100 2 10.53 ll j 100 2 50 2 200 2 V = 320 V (~ j 100 2 Fig. 10-30
