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 cicuit happen?
when 2phases bridge together,that is short circuit
What happen when neutral connect to live?
short circuit
What will happen to a safety device if there is short circiut?
If your reference to a safety device is a fuse, then if there is a short circuit, the circuit will be de energized by the opening of the fuse.
Why a short circuit happen?
Presumably, the current follows a path (a circuit) to do whatever it was "made" to do. If water, for instance, enters the circuit, a shorter path may develop, and the current will (partially) take the short circuit. Or a wire could become lose and short circuit the intended path.
What may happen when two live wires touch each others?
short circuit
What happens in a short circuit occurs in an electric circuit?
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.
What happens when the circuit is complete and the switches are closed?
*Look at the simple circuit illustrated in Figure A-2. What will happen when only switch S1 is closed? Correct Answer= "Nothing will happen-the light bulb won't light up." <<>> If there is a load in the circuit the load will operate. If there is no load in the circuit and it is complete then a short circuit will occur and something in the circuit will burn open. If the circuit is complete and there is a fuse or breaker in the circuit, then the fuse or breaker will open the circuit.
What will happen to the transformer if the rated voltage is applied to the winding during short circuit test?
the winding would burn....
When does short circuit happen?
When a voltage is present between two points in a circuit (electrical outlet, battery, etc.) it normally flows through a load of some resistance to do some work. If instead a pure conductor (usually metal) connects the two points separated by a voltage, a short circuit results. Current through the short circuit is very high and usually results in fire or failure unless protected by a circuit breaker. In low-voltage, low-power electronics a short circuit might not be dangerous but is usually undesirable.
When do you get a short curcuit?
A short circuit occurs when electricity can pass with little resistance between two parts of a circuit where it is not intended to. Typically, it will happen when two uninsulated wires touch accidentally, or a conducting (metal) part contacts two uninsulated parts of the circuit. It could also happen if the circuit is in contact with a conducting fluid such as saltwater. A short circuit can even happen through air if voltage becomes very high, enough to create an electrical "arc", overcoming the resistance of the air. In the worst case, a short circuit connects the positive and negative terminals of a battery or voltage source almost directly, with almost no resistance, and very high current results, which is dangerous. In other cases, the short circuit might not create any danger, because the path of electricity encounters resistance in another part of the circuit. However, the voltage difference across the short will be zero, and the voltage difference across the intended path between the endpoints of the short will also be zero. All the current will flow through the short, and none through the intended path. As a result that part of the circuit probably will not work.
Is a megohm a short circuit?
No. A short circuit would be zero ohms.
