noun
- 1. the ratio of the actual electrical power dissipated by an AC circuit to the product of the r.m.s. values of current and voltage. The difference between the two is caused by reactance in the circuit and represents power that does no useful work.

In electrical engineering, the power factor of an AC power system is defined as the ratio of the real power absorbed by the load to the apparent power flowing in the circuit. Real power is the average of the instantaneous product of voltage and current and represents the capacity of the electricity for performing work.
Apr 19, 2024 · At its core, power factor is a measure of how effectively electrical power is being converted into useful work output in an electrical system. In other words, it indicates the efficiency of the system in delivering power to your devices.
Power factor (PF) is the ratio of working power, measured in kilowatts (kW), to apparent power, measured in kilovolt amperes (kVA). Apparent power, also known as demand, is the measure of the amount of power used to run machinery and equipment during a certain period.
Power factor is simply the measure of evaluating how effectively the incoming electrical power is being utilized in our electrical system. If the power factor is high, then we can say that more effectively the electric power is being used in an electrical system.
The power factor is the cosine of the phase difference between voltage and current, and as a result, the power factor is measured using the formula Power Factor = cosɸ, where ɸ is the phase difference between the voltage and current phasor.
Nov 12, 2018 · We’ll learn what is power factor, what is good and bad power factor, how to compare power factor, the causes of power factor, why and how to fix power factor as well as some example calculations to help you learn electrical engineering.
May 15, 2018 · Power factor is defined as the cosine of angle between the voltage phasor and current phasor in an AC circuit. It is denoted as pf. For an AC circuit, 0≤pf≤1 whereas for DC circuit power factor is always 1. It can be calculated by calculating the ratio of Active Power and Apparent Power.
Definition of power factor. Power factor can be defined as the ratio of real power (Active power) to apparent power. It can also be defined as the absolute value of the cosine of the phase shift between the voltage and current in an AC circuit. It is denoted by the Greek alphabet λ (Lambda).
May 10, 2023 · In electricity, power factor is a measure of the efficiency in transferring electrical energy from a power source to a load. It is defined as the ratio between active power (measured in watts) and apparent power (measured in volt - amperes ).
May 9, 2024 · What is Power Factor? In electrical engineering, the power factor (PF) of an AC electrical power system is defined as the ratio of working power (measured in kilowatts, kW) absorbed by the load to the apparent power (measured in kilovolt amperes, kVA) flowing through the circuit.
