If a 100 Kvar capacitor is installed in the circuit, what will be the new power factor?

To determine the new power factor after installing a 100 kVAR capacitor, it's important to understand how capacitors affect reactive power in an AC circuit. The primary role of a capacitor in power systems is to provide reactive power, which can help counteract the inductive effects caused by motors and transformers. By adding capacitance to an inductive load, you can improve the power factor, which is a measure of how effectively electrical power is being converted into usable work output.

The power factor is calculated as the ratio of real power (measured in kW) to apparent power (measured in kVA). An increase in capacitance will increase the real power factor by reducing the total reactive power required from the source. A power factor of 1.0 (or 100%) represents ideal conditions where all the power supplied by the source is being used effectively, with no reactive power wasted.

In this case, a new power factor of 95% indicates a significant improvement in the circuit's efficiency due to the installation of the capacitor. It suggests that with the added reactive power compensation from the 100 kVAR capacitor, the circuit is now operating much closer to the optimal condition, resulting in better performance and lower energy costs associated with wasted power.
