A fuse is a piece of thin conducting wire connected in the path of a live wire
A French physicist namely “Breguet” was famous for his effort in the initial days of telegraphy. He suggested the utilization of reduced part of conductors to guard telegraph stations against the hits of lighting with liquefying, the slighter wires would guard equipment along with wiring in the building. In the year 1864, lighting installations and telegraph cables can be protected by employing a variety of foil fusible essentials and wires. Finally, Thomas Alva Edison has patented a fuse as an element of his electric distribution system in the year 1890. This article discusses what is a fuse, types of fuses and its applications in various fields.
Types of Fuses and Applications
In the field of electronics or electrical, a fuse is an essential device used in various electrical circuits which gives the protection from the overcurrent. It comprises a strip or a metal wire that dissolves when the heavy flow of current supplies through it. Once this device has functioned in an open circuit, it ought to rewire or changed based on the type of fuse. A fuse is an automatic disconnection of supply which is frequently shortened to ADS. The alternative of the fuse is a stabilizer or circuit breaker, but they have many different characteristics.
Why do we require Fuse?
These are used to prevent the home appliances from the high current or overload damage. If we use a fuse in the homes, the electrical faults cannot happen in the wiring and it doesn’t damage the appliance s from the fire of wire burning. When the fuse gets break or damage, then an abrupt sparkle happens which may direct to damage your home appliances. That is the reason we require different types of fuses to guard our home-appliances against damage.
Working Principle of Fuse
The working principle of the fuse is “heating consequence of the current”. It is fabricated with a lean strip or thread of metallic wire. The connection of the Fuse in an electrical circuit is always in series.
When the too much current is produced due to the heavy flow of current in the electrical circuit, the fuse gets soften and it opens the circuit. The extreme flow of current may direct to the collapse of the wire and prevents the supply.
The fuse can be changed by the new fuse with an appropriate rating. It can be designed with the elements like Cu (copper), Zn (zinc), Al (aluminum) and Ag (silver). They also perform like a circuit breaker for breaking the circuit while the abrupt fault happens in the circuit. This works like a safety measure or protector for humans from risks. Like this, the fuse works.
