Final answer:
An open circuit does not allow electric current to flow, while a closed circuit enables the flow of current through a complete loop.
Explanation:
An open circuit is the type of circuit that cannot conduct an electric current, as it has an incomplete path for the flow of electrons. In contrast, a closed circuit allows current to flow uninterrupted through a complete loop of conducting material. Therefore, in a closed circuit, electric current can pass through and operate devices like lightbulbs or motors.
