A domestic circuit contains a $30\,\text{A}$ fuse. This protects the wiring if the current in the circuit becomes too large. Which wire is the $30\,\text{A}$ fuse fitted into, and what happens when it blows?
- 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 $30\,\text{A}$
