When the voltage across a battery is measured using a D.C potentiometer, the reading shows 1.08 V. But
When the voltage across a battery is measured using a D.C potentiometer, the reading shows 1.08 V. But when the same voltage is measured using a Permanent Magnet Moving Coil (PMMC) voltmeter, the voltmeter reading shows 0.99 V. If the resistance of the voltmeter is 1100 Ohm , the internal resistance of the battery, in Ohm , is (A) 150 (B) 100 (C) 50 (D) 200

Explain V- I method of measurement of medium resistance.
Last answer:
In this method, use suitable source, ammeter and voltmeter and connect them as shown in the above diagram. Take reading of voltmeter and ammeter, then value of resistance = R = V/I Ω To minimise the error take 4 to 5 observation for the same resistance and take their average.
