Q1. What is Power factor
Ans. 
Power factor measures the efficiency of electrical power usage, indicating how effectively electrical energy is converted into useful work.
• Power factor (PF) is defined as the ratio of real power (kW) to apparent power (kVA).

• A power factor of 1 (or 100%) indicates all the power is being effectively converted into work.

• Low power factor can lead to increased energy costs and reduced system capacity.

• Example: A motor with a...read more
