In a potentiometer, the null point is received at 7th wire. If now we have to change the null point at 9th wire, what should we do?

In a potentiometer the null point is received at nth wire. If now we have to change the null poinnt (n+1)th wire, what should we do?

In a potentiometer experiment, to measure the e.m.f. of a cell, the potentiometer consists of six wires each of length 100 cm. The null point is obtained on the third wire. If we want to shift the null point to the 5th wire, then we should

In a potentiometer of 10 wires, the balance point is obtained on the 7^(th) . To shift the balance point to 9^(th) wire, we should

In a potentiometer of 5 wires, the balance point is obtained on the 3rd wire. To shift the balance point to the 4th wire,

In a potentiometer of ten wires each of 1m , the balance point is obtained on the sixth wire. To shift the balance point to eighth wire, we should

In an experiment with a potentiometer, the null point is obtained at a distance of 60 cm along the wire from the common terminal with a leclanche cell. When a shunt resistance of 1 Omega is connected across the cell, the null point shifts to a distance of 30 cm from the common terminal. what is the internal resistance of the cell?

When the resistance in left and right gap of a mere bridge are 101Omega and 1Omega respectively, the null point is found at 99.5 cm. When the resistances are interchanged the null point is now at 0.7cm. Calcualte the end-corrections of the metre bridge.

In a potentiometer experiment of measuring the e.m.f. of a cell, the null point is at 300 cm, when we have a resistance of 200 Omega in series with the cell and the galvanometer. If the resistance is increased to 300 Omega , the null point will be shifted through

In a meter bridge the null point is obtained at the middle point of the wire. If in one gap the resistance is 10 Omega , then the value of resistance in the other gap is :–
