Draw Wheatstone bridge circuit and write down the balancing condition of it. In a meter bridge the balance point is found to be at 40 cm from one end when the resistor at the end is 10 Omega . Find the resistance at the other side. If the galvanometer and the cell are interchanged at the balance condiotion, would it affect the current through the galvanometer?

In a metre-bridge [Fig.], the null point is found to be at a distance of 33.7 cm from A. If now a resistance of 12Omega is connected in parallel with S, the null point occurs at 51.9 cm. Determine the resistance of R and S.

In a metre bridge , null point is obtained at 42.1"cm" on the wire when a 3Omrga resistance is kept in the left gap and a 4Omega resistance in the right gap of the bridge . The null point is shifted towards right by 15.0 cm when the two resistance are interchanged . Determine the end error of the bridge .

Why is it preferred to obtain the null point in a metre bridge between 40 cm and 60cm of the wire ?

In the left gap of a meter bridge there is a coil of copper and in the right gap there is fixed resistance . If the coil of copper is dipped in ice the balance point is obtained at 41.2 cm of the bridge wire . Next the coil is taken of form ice and placed in a container of hoy water . Now the balcnce point is shifted by a distance 8.1 cm towards right . What is the temperature of hot water ? (Tempertaure cofficient of resistance of copper = 42.5xx10^(-4@)C^(-1) . )

Fig. shows a 2.0V potentiometer used for the determination of internal resistance of 1.5V cell- The balance point of the cell in open circuit is 76.3 cm. When a resistor of 9.5Omega is used in the external circuit of the cell, the balance point shifts to 64.8 cm length of the potentiometer wire. Determine the internal resistance of the cell.
