Question

Three loads are connected in parallel cross a 1–phase, 1200 V, 50 Hz supply.
Load 1: Capacitive load, 10 kW and 40 KVAR
Load 2: Inductive load, 35 kW and 120 KVAR
Load 3: Resistive load of 15 kW
What is the total complex power of the circuit?

A.

(10+j80) kVA

B.

(60+j160) kVA

C.

(10–j160) kVA

D.

(60+j80) kVA

Correct option is D


Given:
P = (10+35+15) kW
P = 60 kW
Q = (120–40) KVAR = 80 KVAR
