## Transient processes in linear circuits

Transient processes in electrical circuits are the processes of transition from one work regime to another, that differ with parameters. Transient processes are caused…

## Non-linear DC electric circuits

Non-linear electric circuits contain non-linear components. Non-linear electric components are characterised with non-linear volt-ampere characteristics, as depicted on the figure below. Non-linear components can…

## Magnetic circuits

Magnetic circuit is a set of components, combined in one circuit, that create a magnetic field loop. In calculating magnetic circuits we must remember…

## Non-linear AC circuits

Non-linear AC circuits are AC circuits containing non-linear components. Nonlinear components can be resistive, capacitive, and inductive. Non-linear resistors can be inertial, and non-inertial.…
