Question

which one of the following is the correct option for fill in the blank: closed, broken, open? electric current can flow through a wire only if it forms a loop.

Explanation:

In an electric circuit, for current to flow, the circuit must be complete. A closed loop means the circuit is complete, allowing current to pass. An open loop would mean a break in the circuit (like an open - switch), and a broken loop also implies a non - continuous path. So, based on the basic principle of electric circuits, the correct term is related to a complete path.

Answer:

closed
