Question

2. The three loads in circuit can be describe as follows: Load 1 is absorbing an average power of 7.5KW and 9KVAR (inductive), Load 2 is absorbing an average power of 2.1 kW and 1.8 KVAR (Capacitive), Load 3 consists of a 48 ohms resistor connected in series of reactance of 18.2 ohms. Assume that the voltage of $V_L = 480 \angle 0 V_{rms}$, 60Hz. Find: a. The value of $V_g$ b. The total complex power supplied by the source c. The value of capacitor that needs to be connected in parallel after the $V_g$. to raise the pf to unity.
