Q1. What are the main types of electrical currents?
Ans. 
The main types of electrical currents are AC and DC.
• AC (alternating current) changes direction periodically and is used in household electricity.

• DC (direct current) flows in one direction and is used in batteries and electronic devices.

• Other types of currents include pulsed DC and sinusoidal AC.

• The choice of current type depends on the application and the equipment being used.

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 (in watts) to apparent power (in volt-amperes)

• It indicates the efficiency of electrical power consumption

• A power factor of 1 means all the power is being used effectively, while a power factor less than 1 indicates wastage

• Inductive loads like motors have a lagging power factor, while capaciti...read more
