A domestic circuit has a $30\,\text{A}$ fuse. It safeguards the wiring when the current in the circuit becomes too large. In which wire is the $30\,\text{A}$ fuse fitted, and what happens when it functions?
- Alive wire; disconnects the circuit
- Blive wire; reduces the current to $30\,\text{A}$
- Cneutral wire; disconnects the circuit
- Dneutral wire; reduces the current to $30\,\text{A}$
