Power Factor: Causes and Disadvantages | AC Circuit | Electricity

In this article we will discuss about:- 1. Introduction to Power Factor 2. Causes of Low Power Factor 3. Disadvantages. Introduction to Power Factor: The cosine of the angle between voltage and current in an ac circuit is known as power factor. In an ac circuit, there is generally a phase difference between voltage and current. In an inductive circuit, [...]

Calculating Power Factor in an A.C. Circuit | Electrical Engineering

The below mentioned article provides a formula for calculating power factor in the A.C. circuit. The power in watt absorbed by a d.c. circuit is known when the supply pressure in volt across the circuit is multiplied by the current in ampere flowing through the circuit. But in an a.c. circuit the product of supply pressure and the circuit current [...]
