What is fuse short answer?
Fuse is a piece of wire of a material with a very low melting point. When a high current flows through the circuit due to overloading or short circuit, the wires gets heated and melts. As a result, the circuit is broken and current stops flowing.
What is in a fuse?
A fuse consists of a metal strip or wire fuse element, of small cross-section compared to the circuit conductors, mounted between a pair of electrical terminals, and (usually) enclosed by a non-combustible housing. The fuse is arranged in series to carry all the current passing through the protected circuit.
What is a 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 function of the 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. The fuse contains a piece of wire that melts easily.
What is fuse answer in one word?
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 to do if a fuse has tripped?
Unplug all appliances on that problem circuit and switch off any immersion heaters (if you have one). Switch the tripped switch to the ON position and plug in the appliances one by one until the trip goes again. Leave that appliance unplugged, and have it repaired by a qualified electrician.
Where are the fuses in a fuse box?
Fuses are housed in a fuse box—the precursor to the main service panel found with modern circuit breaker systems. The fuse box is usually located away from main living areas, such as the garage, laundry room, or basement. If you’re unsure whether you have a fuse or breaker box, locate the panel and open it up.
How does a fuse work write?
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. When an excessive current flows in the circuit, it generates heat in the circuit which leads to melt the fuse due to its low melting point, and it also opens the circuit.
What fuse to use?
For an appliance rated as 700W or less, a 3A fuse should be fitted. For appliances above 700W, a 13A fuse should be fitted. One complication of using the 700W rule is that some appliances can draw a higher current when they are first switched on (inrush current).
What is fuse example?
When you overload the circuit in your house by turning on too many different appliances at once and your power to the appliances you are using shuts off, the electrical device that tripped and caused the power to stop to the overloaded circuit is an example of a fuse.
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 fuse what is it made up of?
The fuse is made up of thin strip or strand of metal , whenever the heavy amount of current or an excessive current flow is there in an electrical circuit, the fuse melts and it opens the circuit and disconnects it from the power supply.
What are the types of Fuse?
Low-Voltage Fuse. The low-voltage fuse is usually used in electronic appliances and entertainment gadgets.
What is the principle of Fuse?
Fuses work on the principle of heating effect of current. It consists of a piece of wire called fuse wire made of a metal or an alloy of low melting point. As the current increases beyond a limit, the wire in the electric fuse melts and breaks off.
