A practical voltage source is modeled by an ideal voltage source V_g with an open-circuited effective value of 320 V in series with an output impedance Z_g = 50 + 100 Ω. The source feeds a load Z_l = 200 + j100 Ω. See Fig. 10-30.

(a) Find the average power and reactive power delivered by V_g.

(b) Find the average power and reactive power absorbed by the load.

(c) A reactive element jX is added in parallel to Z_l. Find X such that power delivered to Z_l is maximized.
