Potentiometer wikipedia
WebA potentiometer is a manually adjustable, variable resistor with three terminals. Two terminals are connected to the ends of a resistive element, the third terminal is connected … WebThe Potentiometer is an electric instrument used to measure the EMF (electromotive force) of a given cell, the internal resistance of a cell. And also it is used to compare the EMFs of different cells. It can also use as a variable resistor in most of applications.

WebPotentiometers have three terminals, but can be used as a normal two-terminal resistor by joining the wiper to one of the other terminals, or just using two terminals. Trimpot is a registered trademark of Bourns, Inc., [2] and the device was patented by Marlan Bourns in 1952. The term has since become generic . WebWhat is Potentiometer Taper? Potentiometer taper is the relation between the position of the sliding contact and the resistance of a pot. In the majority of variable resistors available this is a linear relationship, meaning that the relative position is equal to the resistance ratio.
