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?

Text Solution

Verified by Experts

The correct Answer is:
320
In case of zero deflection in galvanometer
` V_(AJ) = (E )/(2), iR_(AJ) = (E )/(2) ,((E )/( 15 r +r)) ((15r)/(600)) AJ = (E )/(2)`
` AJ =320 cm`
