potentiometeris an electric device which isusedto regulate EMF and internal resistance of a given cell. This helps in providing a variable resistance and therefore, a variable potential difference arising between two points in an electric circuit.
Themeter bridgeuses the sameprincipleas the WheatstoneBridge. It is used to find the unknown Resistance of the Material. ... Now until the galvanometer shows a zero or null deflection, adjust the value of resistance in the resistance box and slide the jockey through the wire
