What is a short circuit easy definition?
short circuit. noun. Definition of short circuit (Entry 2 of 2) : a connection of comparatively low resistance accidentally or intentionally made between points on a circuit between which the resistance is normally much greater.
What is the best definition of a short circuit?
The definition of a short circuit is a connection on an electric circuit that allows a current to follow an unplanned or accidental path. An example of a short circuit is a storm damaging a power line and cutting off electricity.
What is short circuit and open circuit?
A short circuit implies that the two terminals are externally connected with resistance R=0 , the same as an ideal wire. This means there is zero voltage difference for any current value. An open circuit implies that the two terminals are points are externally disconnected, which is equivalent to a resistance R=∞ .
How does a short circuit occur?
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 can you prevent a short circuit?
There are many steps one can take to prevent short circuits, here are some of them.
- Unplug Electronics When Not in Use: This is one of the easiest methods to prevent short circuits in your home.
- Install Fuses:
- Install Magneto-Thermal Switches:
- Have Grounded Outlets:

What does short circuit mean?
short circuit. n. (Electronics) a faulty or accidental connection between two points of different potential in an electric circuit, bypassing the load and establishing a path of low resistance through which an excessive current can flow. It can cause damage to the components if the circuit is not protected by a fuse.
What causes an electrical short?
In addition to being caused by worn insulation, an electrical short can also occur when a circuit is not wired properly, as for example when someone fails to notice that the metal lining of an electrical outlet is in contact with one of the wires. Shorts can also be created by damage.
What is short circuit in electronics?
A short circuit (sometimes abbreviated to short or s/c) is an electrical circuit that allows a current to travel along an unintended path with no or very low electrical impedance.
