Electric charge will flow in an electric circuit when
A)electric resistance is low.
B)a potential difference exists.
C)the circuit is grounded.
D)electric devices in the circuit are not defective.

Question

Quizplus · Accepted Answer

Electric charge will flow in an electric circuit only when there is a potential difference between two points. This potential difference creates an electric field which exerts a force on the charge carriers (usually electrons) and causes them to move through the circuit. Resistance affects the flow of charge by opposing the movement of charge carriers, but it does not determine whether charge will flow or not. Grounding and device defects are also not directly related to the flow of charge in a circuit.
