A short circuit is simply a circuit in which the resistance is substantially low. This means that the current of electrons flows far too fast and overheats. This can also form electric arcs (electrons jumping from one point to another). Three common results of short circuits can be: overheating (causing fires), overheating (causing explosions), and electric arcs (causing electric shock).

∙ 11y agoA short circuit (sometimes abbreviated to short or s/c) in an electrical circuit that allows a current to travel along an unintended path, often where essentially no (or a very low) electrical impedance is encountered. The electrical opposite of a short circuit is an "open circuit", which is an infinite resistance between two nodes. It is common to misuse "short circuit" to describe any electrical malfunction, regardless of the actual problem.

∙ 15y agoYes, a short circuit, or short, is dangerous. A short circuit is a path of much lower (or almost zero) resistance in a circuit. When a short happens, excessive current flows, and (hopefully) a fuse or circuit breaker opens. The problem is that usually a short is the result of a failure of some sort in a piece of equipment. If insulation fails or if something like a semiconductor or other device shorts, lots of current flows in the circuit. But the excessive current can cause arcing, which can start a fire. Equipment is designed to resist the effects of a short by incorporating safety features (fuses, current limiters or the like) or relying on the circuit protection devices in the supply (circuit breakers, disconnects or similar) to open and check the excessive current flow. It's all about what happens in the window between the instant that the short develops and the moment that the protection device opens the circuit. In general, all electrical equipment and appliances are engineered to minimize damage from a short circuit in them. The true goal is to allow them to "fail safely" so that if something does go wrong (as it may eventually), the equipment or appliance can "protect itself" and prevent a disaster (a fire). Yes, the loss of the equipment (because it will have to be repaired or replaced) is an inconvenience. But that probability pales in comparison to what can happen in some sort of fire that attacks a house or other structure because it was set by the shorted apparatus. Significant property damage can result, and even death, if electrical equipment shorts and ignites a fire. Manufacturers need to make money to stay in business, as you know, but they make every effort to develop and market a safe product. They have no interest in liability claims, and will, in general, do all they can to avoid those kinds of incidents. Government regulations, backstopped by the sharp knives wielded by product liability attorneys keep the manufacturers honest in all but the very rarest cases. We (manufacturers, suppliers and society) have come a long way to make the relatively inexpensive electrical products we use every day quite safe, and we're pretty good about not backsliding.

∙ 8y agoA short circuit in an electrical circuit allows a current along a different path from the one intended. Short circuits can because if one of the conductors are hot or smoking then you can become severely burned. and that is why they are dangerous

∙ 11y agoA short circuit occurs when two electrical wires of different voltages touch. This causes excessive current flow. If this is wiring in a building, these wires will heat up and could cause a fire. In higher voltage equipment (such as high voltage transmission lines), a short circuit of a phase to ground will cause ground voltage rise, which can increase step (the voltage between your feet) and touch potential (the voltage between your feet and hand) to lethal levels.

What type f circuit by passes most resistance and large dangerous curent flow?
A short circuit. In a properly installed system the fuse will blow to prevent a fire.
What is a circuit with no load?
An open circuit or a short-circuit (if that circuit is complete).
Can different rating circuit breakers have the same short circuit characteristics?
Yes, different amperage rating circuit breakers can have the same short circuit characteristics.
Can switchboard explosion cause short circuit?
A short circuit is what usually causes a switchboard explosion.
Why is a 'short-circuit'in a mains circuit dangerous?
It is potentially dangerous because it provides a low-resistance path across the supply voltage. That causes excessive current to flow, and if all is well a fuse or circuit-breaker will operate to shut off the supply. Without that there might be enough current to cause a fire.
Why are shortcircuits dangerous?
A short circuit can start a fire.
Why is a short circuit dangerous?
A short circuit will draw a lot of current and produce heat so there is great danger of damage and even fire
What is more dangerous a short circuit or an open circuit?
Open circuit Because, if there's an open, there could be machinery still running, or voltage still present. Short shuts a cct down.
A dangerous circuit with low resistance and high current?
Another name for a circuit with low resistance and high current is a short circuit. It is dangerous because, if you have sufficient energy in the power source, you can damage components and/or cause fires.
Why can short circuits be dangerous?
Because of a tendency of too much current to flow through part of a circuit.
What should be kept handy in case of there is a short 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.
Why are damaged electrical cords dangerous?
because it can can cause fire or electrical shock.
How the tubelights on a vendor's cart work?
a short circuit is brought about when short cut is provided for the current flowing there a as a result current bulb up the dangerous the electro-magnet coils are clus wonder and there is a chance of short circuit hence wire is to be inssulated so no electric currrent stops across and no short curict will be produced
What is a type of circuit where current by passes most resistance and large dangerous current flow?
A short circuit. In a properly installed system the fuse will blow to prevent a fire.
When you will get to know that short circuit will happen?
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 ?
Short circuits are dangerous because?
electricity always "wants" to take the easiest route, this is the route with the least resistance, this is why an insulator does not conduct electricity, it takes to much force for the electricity to travel through. a short circuit is when the easiest route is the wrong route i.e. the body of a lamp rather than the wiring of the lamp. the danger of a short circuit is dependent on the voltage and current of the electricity.
When does short circuit happen?
When a voltage is present between two points in a circuit (electrical outlet, battery, etc.) it normally flows through a load of some resistance to do some work. If instead a pure conductor (usually metal) connects the two points separated by a voltage, a short circuit results. Current through the short circuit is very high and usually results in fire or failure unless protected by a circuit breaker. In low-voltage, low-power electronics a short circuit might not be dangerous but is usually undesirable.
