is potential difference there in the whole circuit or just between the cell?

Expert Answer:

Dear student,

In the case of a battery, charge separation that gives rise to a voltage difference is accomplished by chemical reactions at the electrodes a voltaic cell can be thought of as having a "charge pump" of atomic dimensions at each electrode.

When ever you connect a load or a circuit to this battery, then the potential difference means the potential across the elements in the circuit.
