Publicaciones etiquetadas resistor

The potentiometers have three terminals and are usually used in circuits of low current, for circuits of greater current the rheostats are used. In many electrical devices the potentiometers are what set the output level.

Types of resistors

There are many different types of resistors available, from surface mount chip resistors to large-sized resistors. Resistors that obey the law of ohm are called linear resistors, that is, the value of the resistor does not change with the variable current flowing through it.

What is a resistor?

It is a two-terminal electronic device and has no polarity. Its main function is heat dissipation, a process in which electrical energy is converted into thermal energy, that is heat. The unit of measurement of the resistor is the ohm ().
