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,

Rupturing capacity of a circuit breaker?
the maximum short current that can be safely break by the circuit breaker.
Explain electronic circuit to break the electicity in case of short circuit?
A fuse or a circuit breaker can be added directly after the power source (and possibly a transformer) to do this.
Why you do insulation resistance test?
in order to avoid unwanted short circuit break downs.... short circuit can burn the transformer and motor winding.... Megger is the device used to check the insulation .
Does an electric circuit have a beaker?
Electric circuit need a main circuit breaker that can protect the whole circuit from short circuit even in ground fault. It's safer if you use breaker with built in ground protection.
How do you break earphones without leaving signs of it?
Short circuit the connector with a 12V battery for few seconds!
In a series connection if one component fails the whole circuit fails?
Yes. Open circuit. A: It depends on the failure type a short will not necessarily make an open circuit but rather a non functional circuit.
What happens if there is a short circuit in a parallel circuit?
Incorrect answerThen only one of the lights go out.Correct answerActually ALL the lamps will go out if a short circuit occurs across any branch of a parallel circuit because, if the wiring has been done correctly, a circuit breaker will trip or a fuse will blow to cut off the supply of current to all the lights.The loss of a single lamp indicates a break, not a short circuit.
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 ?
What happens to an ammeter when there is a break in a circuit?
An ammeter reads the current that is flowing through a branch of a circuit. If there is a break within that same branch of the circuit, current will not be able to flow through that branch of the circuit as it forms an incomplete loop, so the ammeter will read 0 A of current. If there is a break in a circuit in a branch that is not connected to the ammeter however, the ammeter will give a higher reading of the current. This is assuming that the break in the other branch does not short out the branch with the ammeter attached, and that the circuit can still form a complete loop without that branch.
What is a break in an electrical circuit called?
A break in an electric circuit is called an open circuit. Electric current will not flow through an open circuit.
What function in a circuit for a switch?
A switch is a make - break device. Its function is a circuit is to make and break the current flow of the circuit that it is in. This action then starts and stops the load that is connected in the circuit.
Is a megohm a short circuit?
No. A short circuit would be zero ohms.
