Description : 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 ... resistance of the battery, in Ohm , is (A) 150 (B) 100 (C) 50 (D) 200

Last Answer : 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, ... resistance of the voltmeter is 1100 Ohm , the internal resistance of the battery, in Ohm , is 100

Description : A rheostat differs from potentiometer in the respect that it?

Last Answer : A rheostat differs from potentiometer in the respect that it has higher wattage rating.

Last Answer : In an AC. co-ordinate potentiometer, the currents in the phase and quadrature potentiometer are adjusted to be out of phase by 90°.
