The fuse element is made of zinc, copper, silver, aluminum, or alloys among these or other various metals to provide stable and predictable characteristics. The fuse ideally would carry its rated current indefinitely, and melt quickly on a small excess.
What is fuse made up of Class 10?
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 .
Why is fuse made of alloy?
An electrical fuse is a safety device in the circuit that protects electrical systems by breaking the connection when a short circuit is occurring. The fuse wire is made up of Sn (tin) and Pb (lead) alloy because of its high resistance and low melting .
Which wire is used in fuse?
Which material is generally used in a fuse wire? Answer: An alloy of lead and tin as it has a low melting point and a very high resistance. An electrical fuse is a circuit protection device that protects electrical circuits by breaking the connection in the event of a short circuit.
What is fuse short answer?
Fuse is a piece of wire of a material with a very low melting point . When a high current flows through the circuit due to overloading or short circuit, the wires gets heated and melts. As a result, the circuit is broken and current stops flowing.
Why is fuse used?
The fuse breaks the circuit if a fault in an appliance causes too much current to flow . This protects the wiring and the appliance if something goes wrong.
Which alloy is used as fuse wire?
Solution: Fuse wire is made of alloy of lead and tin having low melting point of 200°C.
Why is a good fuse made of tin?
Fuse wire is made of a tin-lead alloy and not copper because of the following reasons: 1. They have high resistance due to high resistance the wire heats up quickly , when large current flows. ... They have low melting point which melts and breaks off the circuit if the current is larger than the safety limit.
Can we replace a fuse by a piece of wire?
No, the electrician should not be allowed to replace the fuse in the house with a piece of wire. ... A fused filament must have a low melting point such that it could melt and break in response to a large amount of current. Most of the wires have high melting points and hence a wire cannot be used to replace the fuse.
What do you mean by fuse wire?
Fuse wire is used to break the circuit when the load is high so that higher currents do not damage the appliances. ... Fuse is an essential component is a metal wire or strip that melts when too much current flows through it, thereby stopping or interrupting the current.
Is Nichrome used in fuse?
nichrome has a high melting point due to which it is not used as a fuse wire .. if it will be used then the current through circuit will flow and can damage our home appliances....
What are the 3 types of fuses?
- DC Fuses.
- AC Fuses.
- Cartridge Fuses.
- D – Type Cartridge Fuse.
- HRC (High Rupturing Capacity) Fuse or Link Type Cartridge Fuse.
- High Voltage Fuses.
- Automotive, Blade Type & Bolted Type Fuses.
- SMD Fuses (Surface Mount Fuse), Chip , Radial, and Lead Fuses.
What is fuse and its types?
The main category of Fuses are based on the type of circuit they are used in i.e. AC Fuses and DC Fuses . Again, AC Fuses are divided in to High Voltage (HV) Fuses and Low Voltage (LV) Fuses. High Voltage (HV) AC Fuses are used for voltages above 1000V and Low Voltage (LV) AC Fuses are used for voltages less than 1000V.
What is fuse explain?
In electronics and electrical engineering, a fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit . Its essential component is a metal wire or strip that melts when too much current flows through it, thereby stopping or interrupting the current.
What is fuse and its advantages?
Fuse is cheapest type of protection in an electrical circuit . Fuse needs zero maintenance . Operation of fuse is simple and no complexity is involved. Fuse has the ability to interrupt enormous short circuit current without producing noise, flame, gas or smoke.
What is the role of fuse in our daily life?
A fuse(s) is needed in any electrical system (AC or DC). These protection devices react to the amount of heat being produced by electricity passing through wires and/or components . They are used so as to protect wires and components from the extreme heat produced should there be an electrical overload or short circuit.
