Consider the situation shown in (Figure 1). A 1000-V-rms source delivers power to a load. The load consumes 140 kW with a power factor of 55 percent lagging.
1- Find the phasor II, assuming that the capacitor is not connected to the circuit.
Enter your answer using polar notation. Express argument in degrees.
2-Find the value of the capacitance that must be connected in parallel with the load to achieve a power factor of 100 percent.
Express your answer to three significant figures and include the appropriate units.
3-Usually, power-systems engineers rate capacitances used for power-factor correction in terms of their reactive power rating. What is the rating of this capacitance in kVAR?
Express your answer using three significant figures.
4-Assuming that this capacitance is connected, find the new value for the phasor I.
Enter your answer using polar notation. Express argument in degrees.
