When the wire or foil strip inside a fuse melts, the fuse is said to be __________.

Explanation:
When the current flowing through the fuse exceeds its rating, the thin wire or foil element heats up and melts, opening the circuit. This state is called the fuse being blown. The fuse’s job is to provide a one-time interruption to prevent damage or fire, so after blowing, the device must be replaced with a new fuse of the correct rating. This differs from a circuit breaker, which is designed to be reset after tripping. While you may hear that the circuit is now open after a fuse blows, the standard way to describe the device’s condition is that it has blown.
