Continuity refers to what in an electrical system?

• A. A resistance in a circuit.
• B. A circuit of current flowing through all elements from power source to component and back in an unbroken course.
• C. The storage energy in a capacitor.
• D. The magnetic field around a conductor.

Answer: (B)

Continuity is about having a complete, unbroken path for electrical current. In a working circuit, current must travel from the power source through all components and return to the source, forming a closed loop. If any gap exists—like a broken wire, open switch, or loose connection—the loop is interrupted and current cannot flow. A single resistor or a charged capacitor describes a component or its property, not the presence of a closed path for current. The magnetic field around a conductor relates to current flow but doesn’t define whether the circuit is complete. The essence is an unbroken path that lets current move through all elements and back to the source.
