WebPotentiometer is a three- terminal resistor used for measuring the unknown voltage by comparing it with the known voltage. It is used to compare the electromotive force of two cells, and to measure the potential difference between two points of a given circuit and the internal resistance of a cell. WebPress the jockey at both end of the potentiometer wire and note the deflection in galvanometer. If the galvanometer shows opposite deflection, the connections are correct. Now, gently slide the jockey along the potentiometer wire and stop when null point is obtained. Measure the length l 1 between this point and the end P of the potentiometer. WebPotentiometer is a device used to compare the e.m.f. (electromotive force) of two cells, to measure the internal resistance of a cell, 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. toy balloon fashion
