when the fuse is not working
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 2phases bridge together,that is short circuit
short circuit
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.
short 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.
Circuit breakers trip when there is an overload of electrical current flowing through the circuit, which can happen due to too many devices being plugged in, a short circuit, or a ground fault.
*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.
the winding would burn....
A short circuit occurs when a low-resistance path is created between two points in a circuit, causing excessive current flow. This can happen due to a wire touching another wire, a conductor coming into contact with metal objects, or a component failure. When a short circuit occurs, it can potentially lead to overheating, damage to components, and even fire.
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.
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.
