Power factor (PF) 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 indicating perfect efficiency.

• Low power factor can result in increased energy costs and inefficient use of electrical systems.

Power factor (PF) is a measure of how efficiently electrical power is being consumed by a device or system.

• Power factor is the ratio of real power (kW) to apparent power (kVA) in an electrical system.

• It ranges from 0 to 1, with 1 being ideal where all the power is being used efficiently.

• Low power factor can result in increased energy costs and inefficient use of electrical power.

• Power factor correction techniques like ...read more

Power factor is a measure of how effectively electrical power is being used in a circuit.

• Power factor is the ratio of real power (kW) to apparent power (kVA) in an electrical system.

• It indicates how efficiently power is being converted into useful work.

• A power factor of 1 indicates all the power is being used effectively, while a power factor less than 1 indicates some power is being wasted.

• Power factor correction can ...read more
