Line 1:
A '''potentiometer''' is a variable resistor that can be used as a [[voltage divider]].
The present popular usage of the term '''potentiometer''' (or 'pot' for short) describes an electrical device which has a user-adjustable [[electrical resistance|resistance]]. Usually, this is a three-terminal resistor with a sliding contact in the center (the wiper). If all three terminals are used, it can act as a variable [[voltage divider]]. If only two terminals are used (one side and the wiper), it acts as a variable resistor. Its shortcoming is that of corrosion or wearing of the sliding contact, especially if it is kept in one position.
