How is a fuse put in an electric circuit?
Advertisements
उत्तर
Always put the fuse into the appliance's LIVE WIRE at the beginning of the circuit. When the fuse melts, it will break the connection and save the circuit. Even when the fuse burns (the current stops flowing), the appliance will still be connected to the live wire if the fuse is put in neutral wire. This means that anyone touching the wire could get shocked.
