Potentiometer is an electronic element that is used to control and regulate electrical devices, as changing the electrical resistance can change the output electrical voltage. A potentiometer is a passive element consisting of a sliding contact, a resistor, a contact, and an actuator, which is a knob or lever that rotates or a slider that moves. It is used, for example, in audio systems to control the volume of the sound produced by the audio equipment. It works as a voltage divider.
Potentiometers can be integrated into various electronic devices and with a variety of applications, which predisposes to a variety of types by company and type, such as rotary and sliding, by type of revolutions such as single-turn and multi-turn. They can be built from graphite or carbons, as well as by type of mounting according to the type of device, the place and the work they have to do, they can be embedded in a panel, by soldering THT, SMD or PCB or bulk mounting. p>
Different types of potentiometers can be combined depending on the application and the type of work they need to do.
