WebA potentiometer circuit: G, galvanometer. The potentiometer wire is calibrated using a standard cell whose potential difference is accurately known by determining the position of the slide along the wire which gives a null deflection. The standard cell is replaced by the unknown voltage, and the corresponding new balance point is found. Weba) Potentiometer is more sensitive than a voltmeter. b) The resistance of the potentiometer is less than the voltmeter. c) Potentiometer is cheaper than a voltmeter. d) Potentiometer will not take current from the circuit. Answer: d) Potentiometer will not take current from the circuit. 8) Sensitivity of the potentiometer can be increased by
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.
