Assertion: A potentiometer is preferred over that of a voltmeter for measurement of emf of a cell.
Reason: Potentiometer does not draw any current from the cell.

View answer and explanation

Correct option: A

Both assertion and reason are true and reason is the correct explanation of assertion

Option A is correct because a potentiometer is preferred for measuring emf as it doesn't draw current from the cell, providing a more accurate measurement than a voltmeter.
