Identify the type of circuit that would have no current flow through it.

• A. Complete
• B. Grounded
• C. Open
• D. Short

Answer: (C)

When a circuit contains a break in the conducting path, no current can flow. This situation is called an open circuit: even with a voltage source connected, electrons cannot complete the loop, so the current is zero. A complete circuit provides a closed loop that allows current to flow; a short creates a very low-resistance path that actually draws current, often dangerously high; grounding is a reference or safety path and doesn’t by itself determine whether current flows unless the loop is closed. So, the type that yields no current is the open circuit.
