Activity No. 2:
Three loads are connected in parallel across a 1400 Vrms, 60 Hz single-phase supply as
shown below.

Load 1: Inductive load, 125 kVA at 0.28 power factor.
Load 2: Capacitive load, 10 kW and 40 kvar.
Load 3: Resistive load of 15 kW.
(a) Find the total kW, kvar, kVA, and the supply power factor.
(b) A capacitor of negligible resistance is connected in parallel with the above loads
to improve the power factor to 0.8 lagging. Determine the kvar rating of this ca-
pacitor and the capacitance in uF.
(c) Determine the total current before and after power factor correction.
