Question

In a potentiometer, on moving the jockey from one end to another end of the wire, the deflection in the galvanometer deflection remains in the same direction...what are the two possible faults in the circuit that could result in this observation...??​

✬Potentiometer✬

⇨Potentiometer is an device used for measuring the emf of a cell or potential difference between two points in an electrical circuit accurately.

➛The potential difference (emf) across the potentiometer wire is less than the unknown emf.

⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯

➛Also the negative terminal of the unknown emf is joined with the end of the potentiometer wire, which is connected to the positive terminal of known emf.
