What is potentionometer? How it works and where it is used?
Answers
Answer:
A potentiometer is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. ... Potentiometers are commonly used to control electrical devices such as volume controls on audio equipment.
Answer:
It is an instrument for measuring an electromotive force by balancing it against the potential difference produced by passing a known current through a known variable resistance.
Potentiometers work by varying the position of a sliding contact across a uniform resistance. A potentiometer has the two terminals of the input source fixed to the end of the resistor. To adjust the output voltage the sliding contact gets moved along the resistor on the output side.
Potentiometers are commonly used to control electrical devices such as volume controls on audio equipment. Potentiometers operated by a mechanism can be used as position transducers, for example, in a joystick.
