Participation reward: 2 Wealth. Reward for correct answer: 9 Wealth. Question: What is power factor?
In AC circuits, the cosine of the phase difference (Φ) between voltage and current is called the power factor, denoted by cosΦ. Numerically, the power factor is the ratio of real power to apparent power, that is, cosΦ = P/S
It is a figure used to measure the power efficiency of electrical equipment (including electrical devices in a broad sense, such as transformers and transmission lines in power grids, etc.). The definition formula for power factor: Power factor = Apparent power / Real power.
