WebMeasurement of Resistance using Potentiometer The DC potentiometer method of measurement of resistance is used for measuring the unknown resistance of low value. This can be done by comparing the unknown … WebPotentiometer. Potentiometer is a device used to measure the internal resistance of a cell, to compare the e.m.f. of two cells and potential difference across a resistor. It consists of a long wire of uniform cross sectional area and of 10 m in length. The material of wire should have a high resistivity and low temperature coefficient. Potentiometers are rarely used to directly control significant amounts of power (more than a watt or so). Instead they are used to adjust the level of analog signals (for example volume controls audio equipment), and as control inputs for electronic circuits. For example, a light dimmer uses a potentiometer to control the switching of a TRIAC and so indirectly to control the brightness of lamps. reclining ottoman chair

WebA potentiometer is also commonly referred to as a pot. These potentiometers have three terminal connections. One terminal is connected to a sliding contact called a wiper, and the other two terminals are connected to fixed resistance tracks. wipers can be moved along the resistive track using either linear sliding controls or a rotary “wiper” contact. WebWhen a resistance R is put across a cell of emf s and internal resistance r, the current drawn from the cell will be. I = E/ (R+r) The terminal potential difference V across the terminal A and B of the cell and hence across R will be. V = IR. V (R+r) = εr. r = (ε/V - 1)R.
