An industrial load consisting of a bank of induction motors consumes 50 kW at a power factor of 0.8 lagging from a 220-V,60-Hz, single-phase source. By placing a bank of capacitors in parallel with the load, the resultant power factor is to be raised to 0.95 lagging. Find the net capacitance of the capacitor bank in F that is required.
A single-phase, 120V(rms),60Hz source supplies power to a series R-L circuit consisting of R=10 and L=40mH. (a) Determine the power factor of the circuit and state whether it is lagging or leading. (b) Determine the real and reactive power absorbed by the load. (c) Calculate the peak magnetic energy Wint stored in the inductor by using the expression Wint=L(Irms)2 and check whether the reactive power Q=Wint is satisfied. (Note: The instantaneous magnetic energy storage fluctuates between zero and the peak energy. This energy must be sent twice each cycle to the load from the source by means of reactive power flows.)
A source supplies power to the following three loads connected in parallel: (1) a lighting load drawing 10kW.

A 240 kVA synchronous motor of rated apparent power consumes 95 kW of active power of the power grid. And it is possible to adjust it so that by working with this same active power, it compensates the power factor by providing reactive power (i.e., appearing with a capacitive component). How can you get this? What is the maximum reactive power that it can provide?
