Equivalent two-terminal network
Equivalent two-terminal transformations are transformations that lead to the simplification of complex two-terminal networks with the smallest amount of L, C and R elements. These equivalent networks…
Magnetically related networks – transformers
Often networks contain magnetic elements, for example coils, that can create magnetic induction in the other close placed coils, generating the self-induction EMF. Let's…
Four-terminal networks
Four-terminal network is an abstract element of an electrical circuit, having four terminals - two-input and two-output. The four-terminal network is depicted below. If…
Electronic filter
Electronic filters are four-terminal devices that serve to transfer electrical current between the source and load in a certain frequency range. The transparency range…
Three-phase circuits
Three-phase circuits of voltage supplies are the three connected voltage supplies, with the same magnitude of amplitude and frequency, but shifted to 120 grad.…
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.…
