A closed circuit has which characteristic?

A closed circuit has which characteristic?

• A. No current
• B. Only one path
• C. No voltage
• D. Continuous flow

Answer: (D)

A closed circuit provides a complete loop for charge to move, so current can flow continuously around the circuit. When the path is complete, electrons travel from the source, through the conductors and loads, and back to the source, delivering a steady current. If there’s any break, the circuit opens and the current stops. Having voltage is what drives that current; a closed circuit simply means the path is intact, not that there is no voltage. And multiple paths can exist in a circuit (like in parallel layouts), so a closed circuit isn’t limited to a single path. So the defining characteristic is continuous flow of current.
