Answer:
Because the max. potential difference across the resistance wire of potentiometer is the emf of driver cell. Same way, resistance wire of potentiometer acts a scale to measure potential drop. Thus potential drop across that wire and hence emf of driver cell must be more than the emf to be measured.
