What is short circuit in power supply?
A short circuit is when there is a low resistance connection between two conductors that are supplying electrical power to a circuit. This would generate an excess of voltage streaming and cause excessive flow of current in the power source. The electricity will flow through a ‘short’ route and cause a short circuit.
What is a short circuit in a circuit?
Short circuiting is when an electric current flows down the wrong or unintended path with little to no electrical resistance. It can cause serious damage, fire, and even small-scale explosions. In fact, short circuits are one of the leading causes of structural fires around the world.
What happens if you short circuit something?
Short circuits are a major type of electrical accident that can cause serious damage to your electrical system. They occur when a low-resistance path not suited to carry electricity receives a high-volume electrical current. The result of a short circuit can be appliance damage, electrical shock, or even a fire.
What happen in short circuit?
A short circuit occurs when the current finds a way to bypass the appliance on a path that has little or no resistance—for example, where frayed insulation bares a wire and allows it to touch the frame of the appliance, so the current can flow straight to the ground.
How do you build a short circuit protection?

What are the causes of a short circuit?
Many factors can lead to a short circuit. The following are some of the most common causes: Damaged or old insulation normally makes the live wires, and neutral come in contact, which can result in short circuit. Screw and nail can make insulation to damage and create short circuits.
What are the effects of a short circuit?
Effects of Short-Circuit. When a short-circuit occurs, the current in the system increases to an abnormally high value while the system voltage decreases to a low value. The heavy current due to short-circuit causes excessive heating which may result in fire or explosion.
How does a short circuit affect us?
A short circuit can melt the insulation around a wire and may cause a fire , an explosion, or a release of harmful chemicals from certain power supplies, such as a rechargeable battery or a car battery.
Why is a short circuit called a short circuit?
This condition is known as a “short” circuit because the current is bypassing the full circuit wiring and flowing back immediately to the source by a shorter pathway. For electricians, a short circuit is usually defined as a situation in which a hot wire makes contact with a neutral wire, such as when a hot wire loosens from its connection and makes contact with the neutral wire.
