because current flows through live wire
A fuse should be connected in the live wire, before reaching the appliance.
A fuse is typically connected to the live wire in a circuit. This is done to protect the circuit from an overload or short circuit, as the fuse will blow or trip and cut off the current flow if there is an issue.
Suppose there is a fuse which is connected to a live wire and it breaks some day because of excessive power supply. The light goes off because of that. You think that there is no power supply, but actually the neutral wire is taking current towards you. You carelessly try to repair the fuse, and you get a shock. Thus, neutral wires are not preferred in fuse.
The wire becomes connected to earth. In most situations this would result in a blown fuse.
So that the live wire is isolated when the fuse blows. If a fuse was placed in the neutral, the equipment would still be live when the fuse blows.
A live wire in the audio circuit is touching metal, or connected to ground in some way.
The fuse is connected in series - usually in the live connection.
If the wires are incorrectly connected the idea is that it will blow the fuse.
The wire element of a fuse is ONLY effective if it is connected to each end as the only metallic connection. The insulator is required to hold the wire element, and so that people can install and remove the fuse.
A 'live' or 'hot' wire is a wire that is connected to a power source. This wire supplies voltage to a load ( light bulb, hair dryer, etc.). When the load is also connected a neutral or another live wire this becomes a path for the flow of current (amps) known as a circuit.
Same side as the fuse.
No the subwoofer itself does not contain a fuse. The Amplifier Connected to the sub should consist of a fuse or the power wire leading to the amp should contain one.
