Damage from short circuits can be reduced or prevented by employing fuses, circuit breakers, or other overload protection, which disconnect the power in reaction to excessive current

An insulator is used to cover a bare copper conductor to prevent a short circuit. Where the conductor comes into contact with a grounded object a short circuit will be prevented.

A short circuit happens when there is no resistance in the circuit.

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 ?

When a short circuit occurs the circuit overheats. Short circuits often result in home fires.

open circuit has infinite resistance short circuit has no resistance at all

No. A short circuit would be zero ohms.

An open circuit or a short-circuit (if that circuit is complete).

A short circuit is an interruption in the design of a circuit. The short interferes with the flow of electricity causing feedback through the process.

Short circuit blowing fuse or breaker.

Short Circuit can be dangerous do to the fact that they can start fires.

An example of a kind of short circuit is an arc welding.

There is an overload or short to ground in the circuit.There is an overload or short to ground in the circuit.

Short to ground or overload in the circuit.Short to ground or overload in the circuit.

The current in a short circuit may be very high because the resistance in the short circuit is probably less than the resistance in the original circuit.

Short circuit is when two phases or lines on the power circuit has be abruptly bridged, causing a protected electrical circuit to trip.

A short circuit is defined as a closed circuit where the current does not encounter any significant resistance. A closed circuit is any circuit where current can flow. It doesn't have to be short at all, so long as it carries resistance.

Because a whole circuit needs a short circuit to work. It's like a remote; the remote is the whole circuit and the batteries needed are the short circuit. if those batteries are broken, the remote won't work. In other words, without a short circuit, a whole circuit can not occur successfully. Hope this helped, Charlie the Grey

Yes the generator engine will start and keep running. The generator has to start before the short circuit is sensed. What happens to the generator section on a short circuit condition is that the generator breaker will trip and disconnect the short circuit on the load. <<>> genarator will not start because of short circuit

The current will be higher and voltage will be zero, during short circuit.

Touch any live wire to ground and you will have a short circuit.

A spark from a short circuit can cause a fire .

Yes. Voltage becomes zero in a short circuit.

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
