Assertion is true but reason is flaseD. Both assertion and reason are false
Answer» Correct Answer - A When a voltmeter is connected across the two terminals of a cell, it draws small curent from the cell, so it meausures terminal ptoential differecne between the two terminals of the cell whi8ch is lalways less than the emf of the cell on the other hand when a potnetiometer is uses for the measurement of emf of cell it doies not draw nay current from the cell Hence, it accurateluy measures the emf of cell. Thus a potentiometer is prefferred over a voltmeter.
