In a meter bridge when the resistance in the lift gap, is `2Omega` and an unknown resistance in the right gap, the balance point is obtained at 40 cm from Zero end. On shunting the unknown resistance with `2Omega` find the shift of the balance point on the bridge.

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 .

Keeping a resistance of 2Omega in the left gap of a metre bridge , an unknown resistance is placed in the right gap and the null point is obtained at a distance of 40.0 cm . If no end error is present , what will be the value of the unknown resistance ?

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.

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 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) . )

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 .

If the resistance X and Y (XltY) be placed in the two gaps of a metre bridge , null point is obtained at a length of 20cm . Keeping Y unchanged if a resistance 4X is placed in place of X what will be the position of the null point ?

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.
