A short circuit is a condition whereby a point or section of the circuit offer a short path for current to return to the power supply. It occurs when two or more points or sections of the circuit touches each others (but only and only if that results in drop in resistance to such an extent that it causes excessive current to flow through.

∙ 11y agoA short circuit occurs when excessive current i.n the electrical circuits are the direct touching of the wires. This may happen if the insulation on the wires has come off. This may cause a short circuit.

What happens to an electric motor is it over heats?
If a fuse fails to blow or a cut-off doesn't come into play, the insulation on the wires will melt and cause a short circuit.
Is it true or false that a circuit breaker must be replaced after a short circuit occurs?
A circuit breaker must be reset to ON after a short circuit but does not need to be replaced. It depends on the type of CB. A fuse is also a circuit breaker and it needs to be replaced after a short circuit. Relayed circuit breakers have to be "picked up" after a dropout and need not be replaced as such.
When the conducting path for current flow bypasses the load it is called?
a short
How do you know when you have a circuit?
tuned circuit
In relation to electric what does the term fault protection mean?
Protective devices - relays, CT,PT, isolators, circuit breakers are used for fault protection. Fault protection means If there is a fault in the circuit, the circuit must be cut off before any damage occurs due to fault.
What happens when a short circuit occurs in the oven?
Usually the breaker will trip.
What happens in a circuit?
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.
What is a short circuit in aNn electric circuit?
short circuit simply means, when a positive and the negative electric charge collided or met in a certain point.
How does a short circuit occaur?
Short circuit occurs when positive and negative terminals are connected directly.
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 ?
How does short circuit occur?
short circuit occurs when two wire which consist of one live and neutral wire are in contact with the main and the other end of the wire are touched each other short circuit occurs
What is An example of a short circuit?

How do you generate short circuit current?
A short circuit occurs when the hot side of the supply comes in contact with ground.
Why do you mean by short circuit?
A short circuit is a low resistance connection established by an accidental touching between a line supply and a grounded object in an electric circuit. The current will flow through the low resistance point, bypassing the rest of the circuit. When this happens the circuits over current device should open the circuit.
What is the effect on the current when a short circuit occurs?
The current increases.
What happens when both 110v leads are applied to one side of a 220v electric motor?
The breaker will blow because you are effectively causing a short circuit.
How to test for electric short?
If there is an electric short, the resistance of the circuit would be zero. So you can use an ohm meter to test it.
