(N/A) In a domestic circuit,the live wire carries current at a high potential,while the neutral wire is at zero potential (connected to the earth at the substation). If a fuse is connected to the neutral wire and a short circuit occurs,the fuse will blow,but the appliance will remain connected to the high-potential live wire. This poses a severe risk of electric shock to anyone touching the appliance. By connecting the fuse to the live wire,the entire circuit is disconnected from the power source as soon as the fuse blows,ensuring safety.
