The driver cell of a potentiometer
Did you know?
WebThe balance length on the potentiometer wire was measured, i.e. the length from point A to the point of contact of the jockey when the potentiometer is balanced. 9. The potential difference (V) of the driver cell was changed and the instructions 6, 7 and 8 was repeated. 10. The readings and measurements were recorded in a table. 11. Web(d) The point is not affected by the internal resistance of the driver cell. (e) The method would not work if the driver cell of the potentiometer had an emf of 1.0 V instead of 2.0 V. This is because if the emf of the driver cell of the potentiometer is less than the emf of the other cell, then there would be no balance point on the wire.

WebNov 20, 2024 · 1. becouse of potential drop accros the whole potentiometer wire must be greater than that of the cell under testing otherwise null point will not be attained. 2. Potentiometer does not draw current from the cell under testing thus it behaves like ideal voltmeter whose resistance considered as infinite. 3. accuracy of potentiometer is limited …
WebFigure 6.36 shows a potentiometer with a cell of e.m.f. 2.0 V and internal resistance 0.4 Ω maintaining a potential drop across the resistance wire AB. A standard cell which maintains a constant e.m.f. of 1.02 V (for very moderate currents upto a few uA) gives a balance point at 67.3 cm length of the wire.
