Voltage will exist between any two points in a circuit unless the potential drops to zero.

Question

Quizplus · Accepted Answer

This is because voltage is the difference in electric potential energy per unit charge between two points in a circuit. As long as there is a difference in electric potential energy, there will be voltage between those two points. If the potential drops to zero, then there is no difference in electric potential energy between those two points, and therefore no voltage.
