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.Leer más
It is said that a set of resistors connected in series has the same current flowing through them.Leer más
The color codes help to read resistance, tolerance and voltage, apart from these three values, there is another important parameter required to use the resistance in a circuit, this is the rated power of a resistor.Leer más
We can find many different types of resistors available, to identify or calculate the value of a resistance it is important to have a marking system or using a measuring device such as the ohmmeter.
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.Leer más
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 (Ω).Leer más
