In a potentiometer experiment, the galvanometer deflection stays in the same direction as the jockey moves from end A to end B (no null point). Two possible faults are: (1) driver-cell emf is less than the unknown emf ; (2) the galvanometer is connected in reverse.
If the galvanometer deflection is greater at B than at A, which fault is present?
If the galvanometer deflection is greater at B than at A, which fault is present?
