By 'fuse', I assume that you are referring to the fuse element (fuse wire), rather than the complete fuse?
A fuse element is an alloy, such as tin and lead. Alloys such as these exhibit what is called 'eutectic' action. This means that the alloy retains the good conductivity (e.g. of the tin), but has a lower melting point (e.g. thanks to the lead).
Fuse wire is usually made with metal that has a low melting point, e.g. tin, to lessen the risk of fire.
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.
tin lead alloybasically tin lead allows are used . but other metals which have low melting point and appropriate resistivity can be used
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.
To change an in-line fuse in a stereo 4-gauge wire, first disconnect the wire from the power source. Locate the existing fuse holder, open it to access the fuse, replace the fuse with a new one of the same rating, and close the holder securely. Reconnect the wire to the power source and ensure the connection is secure.
copper and tin
Fuse wire is usually made with metal that has a low melting point, e.g. tin, to lessen the risk of fire.
A fuse in its simplest form - is simply a short piece of wire that is weaker than the circuit it is protecting. When the current flowing through the circuit exceeds the fuse rating, the fuse wire melts - breaking the circuit.
Because then it wouldn't 'blow' at the prescribed amperage. -A fuse is made with very fine tolerance wire to melt at an EXACT amperage.
yes very safe.add. Fuse wire is usually made of tin-plated copper. The fuse wire may well get warm in service, and a bare copper wire will gradually oxidize and will fail sooner as a consequence.
NO. Usually the positive wire will have the fuse.
The wire may not melt and break if an unsafe current is produced.
The 15 amp fuse.
A circuit breaker does not have a wire fuse in it.
Fuse wire is designed to open under over current conditions. Just like a fuse.
Electric fuse wire is not made of a single metal but an alloy made of tin (63 %) & lead (37 %). The cross sectional area determines the melting point at a certain current (amps) and is also rated as volts / rating.
yes there is a fuse in the fuse box. the wire will lead to it or to the ignition switch. But the fuse to amke the hot wire hot is in the under dash mounted fuse box.
