Resonance frequency in LC circuits

An LC circuit, also called a resonant circuit, tank circuit, or tuned circuit, is an electric circuit consisting of an inductor, represented by the letter ... more

Coupled inductors

The voltage of one of the two nearby coupled inductors

Faraday - Lenz law (for a tightly wound coil of wire)

Electromagnetic induction is the production of an electromotive force across a conductor when it is exposed to a varying magnetic field. The induced ... more

Mutual inductance factor (coils' inductance)

The mutual inductance in relation with the coupling coefficient and the inductance of two coils

... more

Ripple factor (choke)

For the root mean square value of the ripple voltage, the calculation is more involved as the shape of the ripple waveform has a bearing on the result. ... more

Inductance of a solenoid

A solenoid is a coil wound into a tightly packed helix. In physics, the term refers specifically to a long, thin loop of wire, often wrapped around a ... more

Mutual inductance factor

The mutual inductance factor depends on the number of turns each coil and the permeance of the space occupied by the flux

... more

Coil magnetic energy

The magnetic energy stored by a coil carrying a current is given by one half of the inductance of the coil times the square of the current

... more

Self-inductance factor

Self inductance factor of a solenoid depends on the number of turns, the cross section area, the length of the solenoid and the material within the solenoid
