AC resistance and impedance
AC resistance and DC resistance are the opposition offered to the flow of AC and DC currents respectively through a conductor. However, in an AC circuit, the resistance is called impedance….
Real power, Reactive power, and Apparent Power | Power Triangle
In an AC circuit, the total power consumed is called the apparent power. The power triangle is the representation of a right-angle triangle showing the relation between active power, reactive power, and apparent power. Almost…
Electrical Power in AC circuits
Electrical power is the rate at which the work is done or the rate at which the energy is being consumed in a circuit. Generally, all the electrical and electronic…
RL Series circuit
An RL series circuit consists of passive circuit elements such as an inductor and resistance connected together to a source. In an electrical circuit, an inductor opposes the rate of…
Inductors in Parallel
When inductors are connected in parallel, the voltage drop across each inductor would be the same. In the case of inductors in series, the equivalent inductance is determined by adding…
Inductors in Series
Inductors in series have a total inductance value that includes the effect of both the self-inductance and mutual inductance. An inductor is nothing but a coil of wire wound around…
Mutual Inductance and coupling coefficient
Mutual inductance is the basic operating principle of electrical machines such as transformers, motors, and generators. This principle is applied to any electrical component that needs interaction with another magnetic field….
Inductance of a coil
Inductance is the property of an inductor that opposes any change of current through the coil. An inductor has an important property: when the flux linking the coil changes, an…
What is an Inductor?
An inductor is a two-terminal passive electronic component that is capable of storing electrical energy in the form of a magnetic field when current flows through it. It is also…
