You will get a short circuit if two uninsulated parts of the supply conductors, touch each other. You can also get a short circuit if the "hot" supply conductor touches any grounded metallic part of the system.

∙ 10y agoA short circuit will occur when the supply voltage connects directly with the return leg of a circuit bypassing the circuit's load. With no resistive load to hold the current back the amperage goes in to a very high flow very quickly. This is where the over current protection takes over and opens the circuit to cut off the current flow.

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
Will short circuit wasting energy?
Short circuit blowing fuse or breaker.
How can short circuit damage devices?
It depends if the short are before or after the device. The short circuit will cause high amperage trough the device and then blown. (JP)
What is a Winding-To-Ground Short Circuit?
No
Is it possible to do short circuit test of breakers at project site?
Yes, it possible to do a short circuit test of breakers at a project site.
Can short circuit occur when power is not used?
No because a circuit without power applied can only be shown to be a short circuit after the power is applied between the 'right' two points.
What is used in an electrical circuit to prevent a short circuit?
difference between p type and n type semiconducter materialAnswerInsulation is used to prevent a short current. To protect the circuit should a short-circuit fault occur is either a fuse or a circuit breaker.
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
Why does short circuit break whole circuit?
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
When a dead short occur what happens to circuit resistance?
The circuit resistance is likely to gradually drop and in such case it will cause the circuit to burn down.
Can a circuit breaker on my 1992 grand prix cause my headlights to stay on?
No. A circuit breaker is like a fuse, it protects a circuit from a catastrophe if a dead short should occur.
What would happen to the current once a short circuit occur?
Since load current is determined by dividing the supply voltage by the resistance (for d.c., or impedance for a.c.) of the load, a short circuit would theoretically result in an infinite supply current. This is because a short circuit has, theoretically, zero resistance. In practice, however, the current would be cut off by the operation of an overcurrent protective device -such as a fuse or circuit breaker- which would disconnect the short circuit from the supply voltage. A worst-case scenario could occur should you short-circuit a car battery with, say, a spanner (wrench). With no fuse to protect the battery, the resulting short-circuit current, if sustained, may be high enough to cause catastrophic damage to the battery.
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 the fuse work in a plug?
The fuse in a plug is designed to blow and cut off the current in a circuit before the rest of the wiring and components are damaged or burnt-out should a short-circuit occur.
Why fuse will get burnt when phase and neutral get connected?
A fuse is an overcurrent protection device, which protects a circuit by melting in the event of either a sustained overload current, or a short-circuit current. A short-circuit current will occur when a line (not 'phase') conductor makes direct contact with a neutral (or earth) conductor.
What is the function of ecu-ig fuse on 1997 Conquest?
It protects the circuit from from further damage if a direct short or overload should occur.
Is a megohm a short circuit?
No. A short circuit would be zero ohms.
