WebMeasured Voltage Divider. A voltage divider with resistance values of 250 MΩ and 9.615 MΩ will divide 24 volts into portions of 23.1111 volts and 0.8889 volts, respectively. Since the voltmeter is part of that 9.615 MΩ resistance, that is what it will indicate: 0.8889 volts. Now, the voltmeter can only indicate the voltage its connected across. WebThe significant difference between the two is that the potentiometer measures the emf of the circuit whereas voltmeter measures the end terminal voltage of the circuit. The other differences between the potentiometer and the voltmeter are explained below in the comparison chart. The potentiometer works on the principle of the comparison method.
