Electrical theory

Direct start Of all DC electric motors, the main gradation when choosing a method for starting them is

Current, voltage, etc. d.s. self-induction. When an inductance is connected to an alternating current circuit

Comparison of AC and DC The direction of flow of electrical energy is determined by direct and alternating current. Difference

Conductors Conductors are characterized by good electrical conductivity, i.e. a large number of free electrically charged particles (electrons

Basic concepts of an electrician Time to talk about electrical terminology. Knowing it will be useful to you when

An example of calculating the cable cross-section by power is given in the tables: For a conductor with aluminum conductors.

Functional diagrams and basic electrical parameters of microcircuits As noted in the first article of the series, for electrical
