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.
Which type of metal is used in fuse wire?
Fuse wire is made of alloy of lead and tin having low melting point of 200°C.
What is the wire in a fuse made of?
Fuse wire is made up of an alloy of tin/lead which has high resistance and low melting point. Additional information: Tin, lead, silver, copper, zinc, aluminum, and an alloy of lead and tin are other metals that are also used more specifically for making the fuse wire.
Why copper is used in fuse wire?
Copper is used in normal wiring due to its high melting point . Copper with a higher melting point won't melt easily when there is a current overload and thus allow high current to flow through causing extensive damage to the components connected with it.
What is the best material for fuse wire?
| Metal | Silver | Melting Point in Celsius | 980 | Specific Resistance | 16 | Value of Fuse constant k for d in mm | – |
|---|
What is the peculiarity of fuse wire?
Low melting point , high specific resistance. Hint- A fuse is a safety device consisting of a strip of wire that melts and breaks an Electric circuit if the current exceeds the safe value. It protects the circuit from overcurrent. ... This is only possible when the melting point of the wire is low.
Why a fuse is made of very thin wire?
because it only serves as a normal electrical contact on a circuit or cable. To reduce the area and maintain the minimum resistance to generate heat , the fuse is made as thin. Fuse wire should not have high resistance or low resistance.
What happens if the fuse wire is thick?
What happens if the fuse wire is thick? The resistance of a conductor is proportional to its length and inverse proportional to its cross-sectional area. So, If the fuse wires are thick, the larger cross section decreases the resistance across the fuse wire .
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 would happen if we replace the wire in a fuse with thick copper wire?
If the wire inside the fuse (i.e. Tungsten Or Nickrome) is replaced with thick Copper (Cu) wire, it will melt inside and the Glass may break . Because Copper cannot withstand the high electric current.
Why we should not use any wire to make a fuse?
When a high current flows through the circuit due to Overloading or a Short circuit, the wires get heated and melts. As a result, the circuit is broken and current stops flowing. On the other hand, copper wire cannot be used as a fuse wire because it has a high melting point(1094 deg C approx) .
Can you use any metallic wire as a fuse wire?
Tungsten (alloy of tin and lead) is used to make fuse wire. Yes, you can use metallic wire but tungsten has highest melting point.
What material is used to make the fuse wire can you use any metallic wire as a fuse wire give reasons?
Tungsten is used as the fuse wire. Yes, we can utilize any other metals like aluminium, lead, silver, copper, and tin as fuse wire. Explanation: As Tungsten has a highest melting point of almost 7000 degrees Fahrenheit which makes it useful for fuse wires and light-bulb filaments.
Can I replace a fuse with a wire?
You will need to replace it with fuse wire of the same amperage . Any higher and the fuse won't be able to do its job. This could result in an electrical fire. Thread the new fuse wire through the central part of the fuse (where you will have removed the old wire from.)
What is fuse wire used for?
Fuse wire is used to break the circuit when the load is high so that higher currents do not damage the appliances . Complete step-by-step answer: 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.
What is a fuse wire what is the advantage and disadvantage of using a thick fuse wire?
It is a wire made out of a metal like tin or tin alloy having a very low melting point. When a high current flows through a circuit, the fuse wire gets heated or melts due to short-circuiting or overloading. Hence the circuit is broken and the current stops flowing. This saves all the appliances of the circuit.
