Introduction

Lecture



Electrical engineering is a general education discipline that studies the use of electromagnetic phenomena for practical purposes, as well as issues of production, transmission over a distance, and conversion of electrical energy into other types of energy.

Basic concepts of electrical engineering
The electric field is one of the forms of manifestation of the electromagnetic field, characterized by the electric field intensity

E - emf (V)

Potential - energy of a charged particle or node

φ (B)

Voltage or potential difference

U = φа - φв (В)

Current - the directional movement of electric charges. Currents can be: constant, the value and direction of which does not change in time, variables, the value and direction of which changes in time.

I (A)

Resistance R (Ohms)

Conductivity G (Sim)
