The potentiometer wire `AB` is `600` cm long.
a. At what distance from A should be jockey `J` touch the wire to get zero deflection i the galvanometer.
b. If the jockey touches the wire at a distance `560 cm` from A, what will be the current through 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?

A potentiometer wire AB is 100 cm long and has total resistance of 10Omega . If the galvanometer shows zero deflection at the position C , then find value of unknown resistance

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?

A thin uniform wire AB of length 1m , an unknown resistance X and a resistance of 12 Omega are connected by thick conducting strips, as shown in the figure. A battery and a galvanometer (with a sliding jockey connected to it) area also available. Connections are to be made to measure the unknown resistance X using the principle of Wheatstone bridge. Answer the following questions. (a) Are there positive and negative terminals on the galvanometer ? (b) Copy the figure in your answer book and show the battery and the galvanometer (with jockey) connected at apalphariate points. ( c) After apalphariate connections are made, it is found that no deflection takes place in the galvanometer when the sliding jockey touches the wire at a distance of 60 cm from A . Obtain the value of the resistance X .

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?

What is the magnetic induction at a distance of 5 cm from a straight wire carrying a current of 5 mA ?

A thin uniform wire AB of length 1 m , an unknown resistance X and a resistance of 12 Omega are connected by thick conducting strips, as shown in the figure. A battery and a galvanometer (with a sliding jockey connected to it) are also available. Connections are to be made to measure the unknown resistance X . Using the principle of Wheatstone bridge answer the following questions : (a) Are there positive and negative terminals on the galvanometer? (b) Copy the figure in your answer book and show the battery and the galvanometer (with jockey connect at appropriate points. (c) After appropriate connections are made, it is found that no deflection takes place in th, from galvanometer when the sliding jockey touches the wire at a distance of 60 cm from A . Obtain value of the resistance X.
