Give one property that a fuse wire should have

Last updated at May 29, by Teachoo. A fuse is a piece of wire of a material with a very low melting point, that is, it melts and breaks as soon as its temperature gets higher than its melting point. The material used for making fuse have low melting points , hence fuse wires are mainly made up of tin, lead or zinc. A fuse is used in a circuit to avoid overloading or short circuiting. When a current higher than the rating of the fuse flows through it, the fuse wire gets heated and melts. This breaks the circuit and protects the appliances from getting damaged. An ideal fuse must have the following properties. The appliances which work on large current have fuse of higher current ratings. The appliances which work on small current have fuse of smaller current ratings. Learn in your speed, with individual attention - Teachoo Maths 1-on-1 Class.

Explore the importance of fuses in electrical safety, their working mechanism, types, applications, and comparison with circuit breakers. Designed as a fail-safe in the field of electronics, fuses are a crucial component in the overarching scheme of electrical safety. A fuse is essentially a sacrificial element that prevents excessive amounts of current from flowing through an electric circuit, thus protecting the underlying electrical devices from potential damage caused by overcurrent or a short circuit condition. The operating principle of a fuse is based on the electrical properties of the material used in the fuse wire or element. This interrupts the flow of electric current and prevents the overheating of wires, a common cause of electrical fires. Fuses come in various types, each designed to meet specific requirements in different scenarios. Here are some of the most common types:.

The material used for fuse elements must be of low melting point, low ohmic loss, high conductivity or low resistivity , low cost and free from detraction. The material used for making fuse element has a low melting point such as tin, lead, or zinc. A low melting point is, however, available with a high specific resistance metal shown in the table below. The material mainly used for fuse element are tin, lead, silver, copper, zinc, aluminum, and an alloy of lead and tin. An alloy of lead and tin is used for small current rating fuses. For current exceeding 15A this alloy is not used as the diameters of the wire will be larger and after fusing the metal released will be excessive. Beyond 15A rating circuit, copper wire fuses are employed. Copper wire suffers from the drawbacks that it operates at a rather high temperature if a reasonably low fusing factor is desired. There is thus a tendency for the wire to overheat with the result that its cross-sectional area and fusing current are gradually reduced, and premature melting of the wire may occur.

Normally, the ampacity rating of a conductor is a circuit design limit never to be intentionally exceeded, but there is an application where ampacity exceedence is expected: in the case of fuses. A fuse is nothing more than a short length of wire designed to melt and separate in the event of excessive current. Fuses are always connected in series with the component s to be protected from overcurrent, so that when the fuse blows opens it will open the entire circuit and stop current through the component s.
