A spark from a short circuit can cause a fire .
Either you have a short or your circuit is severly overloaded. Either way call an electrician. It sounds like you have a fire hazard.
A short circuit is one that is characterized by extremely low resistance. This will result in the extremely dramatic increase of current. High current will flow until a safety device opens the circuit, or the weakest link in it burns out. And one of the two usually occurs in a moment or two.==Short Circuit happens when the cables of the electrical appliances are worn out or it's not connected properly,a short circuit may occure.A short circuit has a very low resistance that almost all electric current flow through it.It'll affect the operation of the electrical appliances.Owing to the heating effect,the excess electric current would produce a large amount of heat,wihout a fuse or a circuit breaker,a fire may be occured when there's a short circuit.
Shorts are usually a style of clothing that prevents one from exposing private areas otherwise unacceptable in a public setting. Electric shorts look much better when put on gradually or slowly. Another interpretation comes from short meaning small. When a circuit is in the beginning process, it is considered to be an "Electrical short circuit".
In DC inductor is short circuited .
Short circuit ratio is the ratio of field current required for the rated voltage at open circuit to the field current required for the rated armature current at short circuit
If your reference to a safety device is a fuse, then if there is a short circuit, the circuit will be de energized by the opening of the fuse.
To detect and open the circuit if a thermal overload is present and to detect and open the circuit if a short circuit caused by a magnetic increase of flux in the circuit.
The resistance of the winding in the primary of a transformer constitutes a load. As long as there is resistance then there is no short circuit. A short circuit is considered no resistance which develops an instantaneous high current. That is why fuses and breakers are inserted into the circuit to open the high current flow under a short circuit condition.
No, a circuit breaker is a safety device that is used in a circuit to limit the amount of current in an overload or short circuit condition. The number on a breaker is the top end current that the breaker will handle before opening the circuit.
A safety obeserver who has a wooden object to pull you from the live circuit. They must be trained in CPR and know where the circuit breakers are to deactivate the dangerous circuit in case of a mishap.
1. protection against fire hazard from a short-circuit. A short-circuit can be caused by a loose wire, faulty insulation, or faulty wiring. A short-circuit will cause the wires to heat up rapidly, presenting a fire hazard. 2. protection against circuit overloading. Too much current in a wire caused by overloading (plugging in too many high-power appliances, for example) can cause overheating, presenting a fire hazard. Most circuit breakers have a "slow-blow" mode that breaks the circuit if overload continues for too long. 3. on grounded appliances (which have the third prong on the plug), the ground is connected to all exposed conductive material on the appliance. In the event that a loose wire contacts the exposed metal, a short-circuit will occur, and the power will be cut. This protects against accidental electrocution. Circuit breakers do not protect against fire hazards from inferior gauge of wire, glow-faults, or arc-faults. Most do not protect against electrocution hazards from ground-faults (although some do).
1. That if a short circuit occurs we will get a sign before short circuit will happen or not ? 2. what we can do ? 3. how fuse can get a short circuit ? 4. which wires we have to use from preventing short circuit ?
You have a short or an over current condition in the circuit. It could be a wire touching metal, a bad bulb, etc.
You're talking about a "fuse". The fuse doesn't know anything about "short circuit" or "overload". It only knows that the current through it has exceeded its rated value, but nothing about how or why that occurred.
The purpose of a circuit breaker is to open the circuit in the event of an overload. Wires/conductors are only rated for a specific Amperage. If this amperage is exceeded the conductor/wire begins to heat up and given enough time it becomes a fire hazard. For instance a 15 amp breaker will trip once the Amps drawn through that circuit exceed 15 amps. The short answer is to keep you safe.
