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 [Fig.], the null point is found to be at a distance of 33.7 cm from A. Determine the balance point of the bridge if R and S are interchanged

In a metre-bridge [Fig. (a)], the balance point is found to be at 39.5 cm from the end A, when the resistor S is of 12.5Omega Determine the resistance of R. Why are the connections between the resistors in a Wheatstone bridge or metre-bridge made of thick copper strips?

In a meter bridge the balance point is found to the be at 40 cm from one end when the resistor at the end is 15Omega , Find the resistance at the other side .

In a potentimeter arrangment for determining the emf of a cell , the balance point of the cel in open circuit is 350 cm . When a resistance of 9Omega is used in the external circuit of h the balance point shift to 300cm . Determine the internal reistance of the cell .

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 experiment , a null point is obtained at a length of 39.8 cm when a 2Omega resistance is placed in the left gap and a 3Omega resistance in the right gap . If the two resistance are interchanged , the null point is obtained at 60.8 cm . Calculated the end errors of the bridge .

A null point is obtained when two resistors , of resistance r each, are connected in series and placed in the fourth arm of a wheatstone bridge . Now , the resistance R of the third arm is kept fixed ,and r, connected in parallel, are placed in the fourth arm. then a null point is obtained only by interchanging the resistances P and Q , and also the value of r.

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 .

A resistance R = 2Omega is connected to one of the gaps in a metre bridge, which uses a wire of length 1m. An unknown resistance X is connected in the other gap as shown in the figure. The balance point is noticed at 'l' from the positive end of the battery. On interchanging R and X, it is found that the balance point further shifts by 20 cm (away from end A). Neglecting the end correction, calculate the value of unknown resistance X used.
