What is an electric fuse ? How does it work ?

an electric fuse is a metal strip or wire made up of solder which has a very low melting point. the fuse blows or melts when excessive current passes thru the circuit, hence blocking the circuit. this prevents short circuit.

It is the weakest part in an electric circuit which results in melting and hence breaks an electric circuit in use.

When some overloadin g or voltage fluctuations take place, the fuse wire melts. This in turn breaks the electric circuit and hense current stops flowing in the circiut.

Thus, in a way fuse helps in disconnecting an overloaded or faulty electric circuit and hense prevents an electric fire.

Its essential component is a metal wire or strip that melts when too much current flows through it, interrupting thecircuitthat it connects.Short circuits, overloading, mismatched loads, or device failure are the prime reasons for excessive current. Fuses are an alternative tocircuit breakers.

If we switch on all electrical appliances at the same time, they start drawing huge amounts of currents through the source of wire. Therefore, the wire gets heated which may lead to fire. Fire may also be caused when positive or negative terminals of a circuit come in direct contact. Such situations can be very dangerous because they can damage the entire house or the entire building. To prevent such damages a safety device known as electric fuse is inserted in the circuit.

In simple words we can say that a fuse is a safety device used for breaking the circuit during overloading of current.

An electric fuse consists of a wire made up of an alloy of tin and lead with a very low melting point. When current passing through the wire exceeds the maximum limit, it gets heated up and due to its low melting point, it melts and quickly breaks disconnecting the circuit. This prevents damage to appliances or the building.

A fuse is a safety device to prevent excess current flowing in an electric circuit. It consists of a thin metal wire of low resistance and low melting point. When an electrical appliance or some other piece of electrical equipment becomes faulty, therefore allowing an excess electric current to flow through its circuit, this causes the wire inside the fuse to melt and thus break the flow of current.

Fuses, by design are a one-time-use protective device - once they are used ("burn out"), they're worthless. That is why homes typically use circuit breakers: a breaker acts similarly to a fuse in that it opens a circuit when excessive current flows, but - because nothing actually melts inside it - it can then be reset without having to be replaced by a new one, as has to be done for a fuse.

If there were no fuse in the circuit, serious damage could be caused to the wiring which feeds the equipment. It could get so hot that it catches on fire, which might start a fire in the building or vehicle in which the electrical equipment is installed.

A fuse is a small conducting wire of low melting point which protects the household electrical system from getting damaged due to unusual high current.

The unusual high current may be due to short circuit, power fluctuation in the electric line etc.The fuse wire is made of conducting alloy of very low melting point. It is rated according to the desired current required by an appliance. If the current is more than the rated value, the fuse wire heats up and melts to stop the flow of current.

An electric fuse is an electrical safety device that is used for the purpose of preventing a short circuit. It is installed in electrical devices to prevent the device from damage due to excessive flow of current. The fuse consists of a wire with Low melting point, which when subjected to a magnitude of current higher than the current rating of the device, melts to open the circuit, thereby preventing the flow of excess current through the device.

A fuse is a safety device used in electrical appliances to prevent excess flow of current in an electric circuit. The fuse consist of thin metal wire of low resistivity and low melting point. When there is an excess amount of electric current flowing in a circuit, causes the wire inside the fuse to melt and break, thus stopping the flow of current. Fuses are a one time use protective devices. If there is no fuse, it may cause damage, short circuit or electric fire to the device.

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 interrupting the current. It is a sacrificial device; once a fuse has operated it is an open circuit, and it must be replaced or rewired, depending on type.

Fuses have been used as essential safety devices from the early days of electrical engineering. Today there are thousands of different fuse designs which have specific current and voltage ratings, breaking capacity and response times, depending on the application. The time and current operating characteristics of fuses are chosen to provide adequate protection without needless interruption. Wiring regulations usually define a maximum fuse current rating for particular circuits. Short circuits, overloading, mismatched loads, or device failure are the prime reasons for fuse operation.

A fuse is an automatic means of removing power from a faulty system; often abbreviated to ADS (Automatic Disconnection of Supply). Circuit breakers can be used as an alternative design solution to fuses, but have significantly different characteristics.

An electric fuse is an electronic safety device that regulates the current flowing into an appliance not exceed it's safety limit. A first works on the principle of Joule's heating effect. Since, H=I^2RT................{where I= imagnitude of current, R = resistance and T = time period of flow of current. } So, H(heating) is directly proportional to the square of current. Thus where more amount of current filled through a circuit, then due to more heating, the fuse wire melts due to which the circuit is disconnected. Thus it saves the appliance from fusing.

A fuse is exactly the same. It's a thin piece of wire designed to carry a limited electrical current. If you try to pass a higher current through the wire, it'll heat up so much that it burns or melts. When it melts, it breaks the circuit it's fitted to and stops the current flowing.
