Question

in the potentometer experiment at balance condition current will become always zero in​

Answer 1

Answer:

Because when the potential across the scale( potentiometer wire) and the unknown EMF applied are equal ,at equal potentials there is no flow ofcurrent as there is no potential difference between two ends . hence the galvanometer shows 0 reading.
