What is balance point in potentiometer?

In the potentiometer, the balancing point is the point on the slide wire where the galvanometer display zero deflection.

The balance point is identified to determine the unknown EMF of the cell.
In a potentiometer the balance point is determined when the potential difference between positive end to the jockey is equal to the EMF of experimental cell.
