Why electric fuse is used in houses and factories?

because when there is passage of heavy current beyond its safety limit , that time the fuse wire would melt and stop the passage of current / break the circuit.

Why do we use electric fuse in House and factories?

In order to protect your equipment from overload, a Fuse or MCB is used. Suppose, there is an overload in an electrical circuit, what a Fuse and an MCB do is they break the flow of electricity causing the circuit to break.

Why fuse is used in houses?

In electronics and electrical engineering, a fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit. … When a damaged live wire makes contact with a metal case that is connected to ground, a short circuit will form and the fuse will melt.

What is main advantage of using a fuse?

1) It is the cheapest form of protection. 2) It doesn’t need any maintenance . 3) Its operation is completely automatic and requires less time as compared to circuit breakers. 4) The smaller sizes of fuse element impose a current limiting effect under short-circuit conditions.

IT\'S FUNNING:  How much power does an electric towel rail use?

Why we use MCB instead of fuse?

MCB is more sensitive to current than the fuse. It detects any abnormality in the current flow and automatically switches off the electrical circuit. In the case of MCB, the fault zone of the electrical circuit can be easily identified. … But in case of the fuse, the entire fuse wire needs to be replaced.

Where are fuses used in the home?

Ans- The fuses are one of the most important parts of an electric circuit and an electronic system. Here are some uses of a fuse: They are used in home distribution boards, electric devices and electric appliances to prevent any damage due to excess current flow.

What is an electric fuse How does it work and what is its significance?

An electric fuse is a device that is used to protect electric circuits and electricappliances against high current caused by short – circuiting or overloading due to withdrawal of large current.

Why fuse is considered as safety device?

A fuse is an electrical safety device that has the capability to protect an electric circuit from excessive electric current. It is designed to allow current through the circuit, but in the event that the current exceeds some maximum value it will open, severing the circuit.

What are the applications of fuse?

Fuse Applications

  • Used to protect transformers, motors and power system from over-current conditions.
  • In feeders, power transformers, and solar circuits.
  • Electrical appliances and house distribution boards use fuse for domestic purposes.
  • Used in automotive cars, electric vehicles, racing cars, rails.
IT\'S FUNNING:  Question: Is there a nuclear fusion reactor?

Which effect of electric current is used in a safety fuse?

Explanation: The heating effect of electric current is also used in the fuse. It is a safety device used to prevent damage to an electric circuit if a very high current suddenly passes through it.

What are two advantages of using a fuse over a circuit breaker?

Fuses do not have moving parts. They are maintenance-free and do not require periodic checking. In general, fuses are considered more accurate and reliable than circuit breakers.
