A load with an impedance of 20-j15 ohm is fed from a voltage source through a line having an impedance of 1 j2 ohm. The source voltage is 250V. (a) Calculate the load current phasor and voltage phasor; (b) Calculate the average and reactive power delivered to the load; (c) Calculate the average and reactive power consumed by the line; (d) Calculate the average and reactive power supplied by the source

Answer:

(a) vload = 253.06{-5} volts

b) Pload = 2049.38 watts

    Qload = 1536.5var

c) active power absorbed = 137.38watt

   reactive power absorbed by line = 182.64 Var

d) active power delivered by line = 2151.58 watts

    reactive power deliverd = 1331. 96 Var
