what is the use of a fuse wire in an electrical circuit?explain in brief?

Answer 1

in the event of a current surge due to short circuit or other accidents, the fuse will melt due to current overload and break the circuit. in most cases it vaporises with a loud bang.

the fuse is always placed on the live line (not the neutral line) BEFORE the appliance on the electrical circuit. this way, a surging current is stopped before reaching the appliance and potentially destroying it.

its cheaper to replace a 13A fuse that costs a few coins than to get your refrigerator fixed.

Answer 2

A fuse has a few purposes. The first is to protect the device in the event that for some reason it draws a unexpectedly large current.

The second, is to prevent the device from overheating and bursting into flames, thus causing a fire.

The thrid is to protect the electrical circuit to which it is attached, preventing overheating (and resulting fire) of the conductors in that circuit.

Fuses are rated in volts and amperes. There are also specifications as to how much time at a particular load at which the fuse will blow. Correct voltage ratings must be used to allow the fuse to "clear". If a low voltage fuse is used in a high voltage circuit, it's possible that even after the fuse 'blows' that it will still carry current due to ionization or metalization on the glass.

Fuses are much more than the simple glass devices they seem to be, but their common purpose is protection of electrical circuits.

Answer 3

The fuse wire is the weakest point in the circuit, and burns out before the rest of the circuit.
If the circuit "shorts" (two wires touch) or overloads the thin fuse wire burns instead of the rest of the wiring.
It is there basically to stop your wiring from catching on fire, if the circuit becomes overloaded, as happens in a short circuit.

Answer 4

in case you have been talking some common breaker field and the breaker for that circuit became tripped with the intention to do elementary wiring, i might say choose for it. In an previous homestead with an previous fuse field style of issue, you have had distinctive upload-ons from extremely some adjustments by the years. I as quickly as had some fool leave a stay electric cord dangling from the fuse field, and became informed that its ability have been decrease. So there i became working around it drywalling and such, employing the moist dirt, questioning that the cord became lifeless whilst it became stay. that's a miracle that i became no longer electrocuted. So, i might desire to flow via my journey, and say, not at all assume that somebody else has under pressure something top, particularly whilst that's previous wiring in an previous fuse field. So have it regarded at professionally. in case you're able to desire to try this your self, use a multimeter alongside each and every step of ways the place you ought to be exposing your self to electrical energy. i might hate to be certain you performing on somebody's advice whilst your wiring ought to be flow-under pressure in any such way you could probably be injury. good luck!

Answer 5

If cars didn't have fuses, when something shorted out it would probably destroy the whole electrical harness. Something has to give first when you have a short and a 10 cent fuse is a lot better than waiting for the wire to melt. Or for your house to burn down.

Answer 6

a fuse, short for 'fusible link', is a type of overcurrent protection device. It has as its critical component a metal wire or strip that will melt when heated by a prescribed electric current, opening the circuit of which it is a part, and so protecting the circuit from an overcurrent condition.

Answer 7

A fuse wire is a conductor usually of low resistence and low melting point. Whenever there is excessive flow of current in an elctrical circuit the wire heats and melts this causes stoppage of flow of current in the circuit and protects the electrical circuit from being damaged.

Answer 8

If too much current flows in a wire, it may overheat and bad things can happen.

A fuse is made such that if too much current flows in the wire then the fuse will burn and stop the flow of the current in the wire.

Answer 9

This is a protection device that will hopefully protect the electrical circuits when a short occurs. The device will melt open and disallow further electrical current protecting from further electrical damage or fire.

Answer 10

a fuse wire will break the circut if to much juice (power surge) is going through the line to prevent the excess electricity from frying what ever it is plugged into.
