Web9. A potentiometer is better than a voltmeter for measuring emf of a cell. Why? When we balance a cell against a pot wire, There is no current through the cell. The emf is measured then. Now, when we use a voltmeter to measure the emf for the cell, there is a small current which flows through the cell. Thus, we get only the terminal potential. 10. WebStep 9: Measure the total battery voltage, and then measure the voltage between the same two points on the potentiometer (wiper and negative side). Step 10: Divide the potentiometer’s measured output voltage by the measured total voltage. The quotient should be 1/3, the same voltage division ratio set in Step 8.
