What does the no deflection position in the galvanometer of potentiometer experiment tell us about the flow of current ?
Text Solution
Verified by Experts
When the balance point is obtianed on the potentiometer wire, no current flows in the gaolvanometer circuit because the fall of potential across the potnetiometer wire between zero end and balance point position becomes just equal to the emf of the cell, whereas the current in the potentiometer wire continues flowing.
