What is an electric fuse Class 7?

Fuse is a safety device that is a safeguard to all of our electrical appliances. They are made up of special material which melt quickly and break when large electric currents passed through it.

What is an electric fuse answer?

Electric fuse is a safety device used to limit the current in an electric circuit which melts and breaks the circuit whenever there is an excess flow of current through the circuit.

What are the 3 types of fuses?

Different Types of Fuses – Constriction, Working & Characteristics

  • 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 electrical fuse in science?

An electric fuse is an electric device which interrupts the flow of current in an electric circuit. It is installed in a circuit to stop the flow of excessive current. A fuse is usually a short piece of wire.

What is electric fuse and its use?

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 the use of electric fuse?

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. The fuse contains a piece of wire that melts easily.

Why is an electric fuse required in all electrical appliances?

This wire is chosen such that it melts when excess current passes through the electrical appliance. When excess current passes through the electrical appliance, it can damage the appliance permanently as well. … Hence an electric fuse required in all electrical appliances for the protective reason of the appliance.

What are characteristics of fuse?

Characteristics of Fuse Element:

  • low melting point e.g., tin, lead.
  • high conductivity e.g., silver, copper.
  • free from deterioration due to oxidation e.g., silver.
  • low cost e.g., lead, tin, copper.

What kind of fuses are there?

Fuses can be divided into two major categories, AC fuses, and DC fuses.

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.

What is the fuse app?

Fuse is a mobile app that allows you to send images and videos wirelessly from your iPhone or Android devices directly to Camtasia or Snagit.

How do you make an electrical fuse?

Place one end of the strip of fuse wire in the center of the blown fuse lengthwise. Wrap the strip of fuse wire around the fuse so it covers the two metal ends of the blown fuse. The fuse wire goes around the fuse but doesn’t quite meet up to the end where you started.
