A 10 m long potentiometer wire is connected to a battery having a steady voltage . A leclanche cell is balanced at 4 m length of the wire . If the length is kept the same, but its cross - section is doubled the null point will be obtained at .

If the length of a wire is doubled and its cross-section is also doubled, then its resistance will

A potentiometer having a wire of 4m length is connected to the terminals of a battery with a steady voltage. A leclanche cell has a null point at 1m. If the length of the potentiometer wire is increased by 1m. The position of the null point is

A potentiometer having a wire of 4 m lengths is connected to the terminals of a battery with steady voltage. A leclanche cell has a null point at 1m. If the length of the potentiometer wire is increased by 1 m, the position of the null points is

A potentiometer , with a wire of length 10 m, is connected to an accululator of steady voltage. A lenchlanche cell gives a null point at 7.5 m If the length of the potentiometer wire is increaseed by 1 m, find the new posistion of the balance point.

A potentiometer , with a wire of length 10 m, is connected to an accululator of steady voltage. A lenchlanche cell gives a null point at 7.5 m If the length of the potentiometer wire is increaseed by 1 m, find the new posistion of the null point.

A ten meter long potentiometer wire is connected to accumulator of emf 2volts and negligible internal resistance. A lechlanche cell gives null point at 4 meter. If the diameter of the wire is doubled keeping the length same. The position of new null point will be

A potentiometer having a wire 10 m long stretched on it is connected to a battery having a steady voltage. A length of potentiometer wire is increase by 100 cm , find the new position of null point.
