Receivers of electrical energy:

a) with irreversible processes of conversion of electrical energy into other types of energy:
Resistor, (the conductor's resistance to electric current), electrical energy is converted into heat.

Resistor symbol



1-type device:
Р - constant, RP - variable, ТР - thermistor, etc.
2-material:
1 - non-wired, 2 - wire, etc.
3-ordinal development number
Example designation: P1-26 (fixed non-wired resistor).

The main parameters of resistors
nominal resistance and tolerance on the value of resistance
rated power
temperature coefficient of resistance
Values ​​of nominal resistances are selected from the series of resistances Е6, Е12, Е24, Е48, Е96, Е192

Incandescent lamp, electrical energy is converted into light, heat energy, etc.



b) with reversible processes of electrical and magnetic energy conversion

A capacitor is an element of an electrical circuit,
intended to be used by him
electrical capacitance

Symbol Capacitors



Capacitor, with capacity

C = q / u.

Capacity of a flat capacitor
