Question

The two loads in the circuit shown can be described as follows:              Load 1 absorbs 8 kW at a leading power factor of 0.8. Load 2 absorbs 20
kVA at a lagging power factor of 0.6.

1. Determine the power factor of the two loads in parallel.
2. Determine the apparent power required to supply the loads, the
magnitude of the current, Is, and the average power loss in thetransmission line.
3. Given that the frequency of the source is 60 Hz, compute the value of
the capacitor that would correct the power factor to 1 if placed in
parallel with the two loads. Recalculate the values in (b) for the load
with the corrected power factor.
