Electrons in a circuit always need a path to move when a potential difference is established.
True
In a circuit, the electrons will flow from the negative terminal to the positive terminal on the application of a potential difference, provided a conducting path is provided. The conducting path can be a metallic wire or any other medium which is a conductor of electricity. If the path is broken then the flow of electrons will stop too, as in the case of an open circuit, where the switch is open.
