*P5.75. Two loads-A and B - are connected in par- allel across a 1-kV rms 60-Hz line, as shown in Figure P5.75. Load A consumes 10 kW with a 90-percent-lagging power factor. Load B has an apparent power of 15 kVA with an 80- percent-lagging power factor. Find the power, reactive power, and apparent power deliv- ered by the source. What is the power factor seen by the source? 1 kV rms 60 Hz + Line 0 0 A B Figure P5.75 IB 4

P5.46. Find the phasors for the voltage and the cur- rents of the circuit shown in Figure P5.46. Construct a phasor diagram showing Is, V. IR, and IL. What is the phase relationship between V and Is? 1 H 200 2 0.5 sin(100r) (1)a Figure P5.46

What is the significance of reactive power in power systems, and how is it managed?

A load is connected across a 25,000 Volts, 60 Hz source and draws a current of 90 A rms. If the power factor of the load is to be corrected from 0.75 lagging to 0.9 lagging, find the capacitance of the capacitor to be connected in parallel with the load.

Q2: Write a lecture for teaching the complex power fed to an (R-L) load fed from an AC power source of sinusoidal voltage and current waveforms, describing its three components, their waveforms, their power triangle, and units.
