In potentiometer circuit, the value of the length AJ for which galvanometer shows null deflection is (RAC = 4.1, AC = 100 cm) 5 V А. 2.5 V

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

Figure- 3.287 shows a potentiometer with length of wire Im and resistance 10 Omega . In this system find length PC when galvanometer shows null deflection.

In the meter bridge circuit shown in figure- 3.281 find the length AC at null deflection in galvanometer.

In the given circuit, when the galvanometer G shows no deflection, the current in the 5 Omega resistance is ,

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 )

A simple potentiometer circuit is shown in the figure. The internal resistance of 5 V battery is 0.6 Omega wire of length 4 m and resistance 0.5 Omega per meter. The length AB for which galvanometer shows zero deflection is

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
