Q1. What is power factor
Ans. 
Power factor is a measure of how effectively electrical power is being used in a circuit.
• Power factor is the ratio of real power to apparent power in a circuit.

• It is a number between 0 and 1, with 1 representing perfect efficiency.

• Low power factor indicates inefficient use of electrical power.

• Power factor can be improved by using power factor correction devices like capacitors.

• Formula: Power Factor = Real Power / Appar
