Your question: What is electric fuse what is 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 a 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.

What is electric fuse and write down the uses?

The electric fuse is a piece of wire having a very low melting point and high resistance. An electric fuse is used as a safety device for the protection of electric circuits and appliances due to short-circuiting or overloading of the electric circuits.

What is 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 fuse and state its uses?

FUSE: “Is a safety device that is used to limit the current in an electric circuit. PURPOSE OF FUSE IN HOUSEHOLD CIRCUIT: It safeguards the circuit and the appliance connected in the circuit from being damaged if the current in the circuit exceeds the specified value due to voltage fluctuation or short-circuiting.

What is electric fuse Class 10?

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.

What is the use of electric fuse Class 10?

A fuse is used in a circuit to avoid overloading or short circuiting. When a current higher than the rating of the fuse flows through it, the fuse wire gets heated and melts. This breaks the circuit and protects the appliances from getting damaged.

What is fuse short answer?

A fuse is a safety device in an electric plug or circuit. It contains a piece of wire which melts when there is a fault so that the flow of electricity stops. … When things fuse or are fused, they join together physically or chemically, usually to become one thing.

What are electric fuses and on what basis does it works what is their importance and also name fuses of different kinds used for different purposes any two?

The fuse is the current interrupting devices which break or open the circuit by fusing the element and thus remove the faulty device from the main supply circuit. The fuses are mainly classified into two types, depends on the input supply voltages they are the AC fuses and the DC fuses.

What is electric fuse made up of?

Answer: Tin and lead 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.

What is short circuiting class 10th?

Short circuiting: It occurs sometimes that the live and neutral wires come in contact with each other, and this result is called short circuiting. In such instances, the resistance of a circuit decreases to an extremely small value. … To avoid this fire, an electric fuse is used in the circuit.

What is electric fuse What is its role in electric circuit should it be placed on neutral wire or on live wire justify your answer?

Fuse should be placed on live wire because the live wire has the higher voltage. If the live wire is damaged inside the appliance and a large current is created, then the fuse needs to be in this part of the circuit so that it can blow.

What is the use of electric fuse How does it connect with the circuit?

Answer: Fuses are always connected in series with the components to be protected from overcurrent, so that when the fuse blows (opens) it will open the entire circuit and stop current through the components.
