what is fuse? why fuse is used ?

Answer:
A fuse is a component that is used to protect any device or circuit from any damage. In case of excessive current in any device or any type of fault, the fuse stops its supply. So that the loss can be avoided. All equipment uses are of different types. It depends on the device. Depending on the type of fuse he needs and the current used in the fuse equipment, or depending on how much load the device takes, it is fused.
Explanation:
The fuse is always placed in sequence (Series) of any circuit or device. When a fuse is applied to any device, the fuse is applied on the basis of its normal current load. If there is any defect in the device, when its current load increases, the fuse will burn and the supply of the equipment is stopped. . Very often, short circuit is done in open for some reason. So that the equipment can suffer a lot of damage. Fuse is used to protect this damage. Whenever the device has a short circuit. So the first fuse is ignited. And the equipment supply stops at the same time. So fuse is used everywhere. And you should use it in your home too.
Answer:
A fuse is an electrical safety device built around a conductive strip that is designed to melt and separate in the event of excessive current. Fuses are always connected in series with the component(s) to be protected from overcurrent, so that when the fuse blows (opens) it will open the entire circuit and stop current through the component(s). A fuse connected in one branch of a parallel circuit, of course, would not affect current through any of the other branches.
Normally, the thin piece of fuse wire is contained within a safety sheath to minimize hazards of arc blast if the wire burns open with violent force, as can happen in the case of severe overcurrents. In the case of small automotive fuses, the sheath is transparent so that the fusible element can be visually inspected. Residential wiring used to commonly employ screw-in fuses with glass bodies and a thin, narrow metal foil strip in the middle. A photograph showing both types of fuses is shown here:
Explanation:
Cartridge type fuses are popular in automotive applications, and in industrial applications when constructed with sheath materials other than glass. Because fuses are designed to “fail” open when their current rating is exceeded, they are typically designed to be replaced easily in a circuit. This means they will be inserted into some type of holder rather than being directly soldered or bolted to the circuit conductors. The following is a photograph showing a couple of glass cartridge fuses in a multi-fuse holder:
