What is the function of the fuses?
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.
What is the function of fuse short answer?
The basic function of a fuse is to prevent fire.It breaks the electric circuit if there occurs a fault in an electrical appliance that causes too much current flow. The fuse protects the wiring and the appliance if anything goes wrong.
What is the function of fuse for 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. In order to make a battery the negative terminal of one cell is connected to the positive terminal of the other cell.
What is fuse and its importance?
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 principle of fuse?
heating effect of electric current
An electric fuse is based on the principle of heating effect of electric current. It is made up of thin metallic wire of non-combustible material. A fuse is always connected between the ends of the terminal in a series connection with the circuit.
What is the main function of Fuse?
The main function of the fuse is to protect the electrical circuits from the overflow of current . In a real-time situation, the flow of current during the wires may not be consistent all the time. In those situations, the device may get damaged from overheat.
What is the function of a fuse in an electric circuit?
Functions of Fuse. In the field of electrical engineering, a fuse is a device that aims at providing over-current protection in an operational electric circuit. It works on the principle where the fuse, essentially made up of a thin metal strip or the wire gets heated up when too much current flows through it and thereafter melts,…
What are the advantages of a fuse?
Advantages: Fuse is cheapest type of protection in an electrical circuit Fuse needs zero maintenance Operation of fuse is simple and no complexity is involved Fuse has the ability to interrupt enormous short circuit current without producing noise, flame, gas or smoke The operation time of fuse can be made much smaller than operation of circuit breaker.
What is often used instead of a fuse?
Today, circuit breakers are used in homes instead of fuses. The main reason is because a circuit breaker can be re-used. Once a fuse blows, it has to be replaced.
