Q1. A fuse in a circuit mainly protects wiring by doing what during a large overcurrent?
Answer: Melting or opening to stop the current path
Explanation: A fuse contains a thin wire that melts when the current exceeds a safe threshold, opening the circuit and stopping current flow before the wiring can overheat and cause a fire. Once blown, a fuse must be replaced; circuit breakers serve the same protective function but can be reset.
