ASVAB Practice Test

When current flow is interrupted by a blown fuse, what becomes of the circuit?

1. Closed

2. Open

3. Short

4. Active

The correct answer is: Open

When current flow is interrupted by a blown fuse, the circuit becomes open, meaning that there is no longer a continuous path for the electricity to flow. Option A is incorrect because a closed circuit would allow the current to flow without interruption. Option C is incorrect because a short circuit is an abnormal connection between two different points in the circuit, rather than an interruption. Option D is incorrect because while the circuit may have been active before the fuse blew, it becomes inactive once the flow of current is interrupted.
