You asked: On what principle does an electric fuse work?

An electric fuse operates on the principle of heating effect of electric current. During normal condition, the fuse element is at a temperature below its melting point. But when a short circuit or overload occurs, an excessive current will flow through fuse element.

On what principle do electric fuse work Why do we use electric fuse in our household circuits?

An electric fuse in households works on the principle of Joule’s heating that heat produced due to the excess current flowing through it melts the fuse wire which cut off the circuit and hence the appliance is prevented from damage.

What is an electric fuse and how does it work class 10?

Solution: 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 do you mean by electric fuse?

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 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.

Which wire is used in electric 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.

Which of the following is not suitable for a fuse wire?

Higher resistance than rest of the point.

Where do we connect a fuse in an electrical circuit?

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).

Which one of the given fuse is bigger?

Which one of the given fuse is bigger? The main difference between the DC Fuses and AC Fuses is the size of the fuse. … This will minimize the chance of arc and since the distance between the electrodes is increased, the size of the DC Fuses is comparatively large.

Does electric fuse works on magnetic effect of electric current?

Complete answer:

Since it melts, the connection between the circuit is lost. This is due to the heating effect of the electric current. It means the current flowing through the resistance conductor produces the heat.

What is an electric fuse class 10th?

Electric fuse is a small piece of wire of a material having low melting point and high resistance. The device protects the circuit from overloading and short circuiting. A fuse wire is made of pure tin or of an alloy of copper and tin. 640 Views.

What is the use of electric fuse Class 7?

A fuse is a safety device which limits current in circuit as a result it prevents damages to electrical circuits and possible fires. Fuses used in electrical appliances.

What is the role of an electric switch?

The function of an electric switch is to regulate the current between the load and source of power. The power source is the electrons that push through the circuits. The voltage is the quantity of force or pressure applied by the power source.
