Understand ac power concepts, their relationships to one another, and how to calculate them in a circuit
The load impedance in the circuit shown is shunted by a capacitor
having a capacitive reactance of −52 Ω. Calculate:
1. a) the rms phasors VL and IL,
2. b) the average power and magnetizing reactive power absorbed by
the (39+j26) Ω load impedance,
3. c) the average power and magnetizing reactive power absorbed by
the (1+j4) Ω line impedance, 4. d) the average power and magnetizing reactive power delivered by
the source, and
5. e) the magnetizing reactive power delivered by the shunting
capacitor.
