To have an electric charge flow through a wire, there must be a difference in electric potential, often caused by a voltage source like a battery. This voltage creates an electric field that pushes charges through the wire. Resistance may affect the flow, but it is not a prerequisite for the movement of electric charge. ;
For electric charge to flow through a wire, there must be a difference in electric potential (voltage). This potential difference causes electrons to move, creating an electric current. Resistance affects how easily the current can flow, but it is not required for charge movement.
