In the circuit, given figure below the length of the wire AB = 400 cm. Where should the jockey J be placed, so that the galvanometer shows a zero deflection?

The potentiometer wire AB shown in figure is 40 cm long. Where should the free end of the galvanometer be connected on AB so that the galvanometer may show zero deflection?

In the circuit shown, the length of AB is 100 cm. The length j_1 for which the galvanometer shows zero deflection is __________ cm.

The potentiometer wire AB shown in figure is 40 cm long. Where the free end of the galvanometer should be connected on AB so that the galvanometer may show zero deflection?

In the potentiometer circuit shown in the figure the internal resistance of the 6V battery is 1Omega and length of the wire AB is 100 cm . When AD = 60 cm , the galvanometer shows no deflection . The EMF of the cell C is (the resistance of the wire AB is 2Omega )

For the potentiometer arrangement shown in the figure, length of wire AB is 100 cm and its resistance is 9 Omega . Find the length AC for which the galvanometer G will show zero deflection.

Consider the potentiometer circuit arranged as in figure. The potentiometer wire is 600cm long. At what distance from the point A should the jockey touch the wire to get zero deflection in the galvanometer? b) If the jockey touches the wire at a distance of 560cm from A, What will be the current in the galvanometer?

In the adjacent circuit a resisttance R is used. Initially with 'wire AB' not in the circuit, the galavanometer shhows a deflection of d divisions. Now, the wire AB is conneted parallel to the galvanometer and the galvanometer shows a deflection defiction nearly d/2 divisions. Therefore

The potentiometer wire AB is 600 cm long . At what distance (in cm) from A should the jockey J touch the wire to get zero deflection in the galvanometer?

The potentiometer wire AB is 600cm long. At what distance (in cm) from A should the jockey J touch the wire to get zero deflection in the galvanometer?

Figure alongside shows a uniform manganin wire XY of length 100 cm and resistance 9Omega , connected to an accumulator D of emf 4 V and internal resistance 1Omega through a variable resistance R. E is a cell of emf 1.8 V connected to the wire XY via a jockey J and a central zero galvanometer G. It is found that the galvanometer shows no deflection when XJ = 80 cm. Find the value of R.
