What is the difference in an open circuit and a short circuit?
an open circuit is a circuit that does not complete the circle. an open circuit does not do the job as the electricity stands still a short circuit is a circuit that wires have crossed and the electricity takes the shortest path. and does not complete all of the points on the circuit
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.
How can an ammeter cause a short circuit?
An ammeter can cause a short circuit if it is connected in parallel instead of in series with the circuit being measured. This can create a low resistance path for the current to flow, bypassing the intended circuit and causing a short circuit.
What happens in a circuit?
A short circuit is one that is characterized by extremely low resistance. This will result in the extremely dramatic increase of current. High current will flow until a safety device opens the circuit, or the weakest link in it burns out. And one of the two usually occurs in a moment or two.==Short Circuit happens when the cables of the electrical appliances are worn out or it's not connected properly,a short circuit may occure.A short circuit has a very low resistance that almost all electric current flow through it.It'll affect the operation of the electrical appliances.Owing to the heating effect,the excess electric current would produce a large amount of heat,wihout a fuse or a circuit breaker,a fire may be occured when there's a short circuit.
What circuit fault allows current to flow but at a reduced rate?
A partial short circuit can allow current to flow at a reduced rate. This happens when there is a partial break in the circuit that does not completely prevent current flow but results in higher resistance and lower current flow than normal.
What is output short circuit current?
The output short circuit current is the solar cell's current when the voltage is zero, or when it, is short circuited.
Why might the current in a short circuit be higher than the current in the original 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.
What is the effect of transformer impedance on short circuit current?
Short circuit current will increase a lot.
What is short circuit ratio of an alternator?
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
How short circuit current measure?
In shortg circuit current is infinitive.
What term is used to describe current that can flow in a circuit as a result of an undesired short circuit?
Generically, it's an 'overcurrent'; specifically, it's a 'short-circuit current'.
Will voltage or current be higher in a circuit during short circuit?
Since a short circuit is, essentially, a zero impedance connection between nodes, the current in a short circuit is limited only by the ability of the source. In the case of an ideal voltage source connected to an ideal short circuit, you would have infinite amperes.
What is the effect on the current when a short circuit occurs?
The current increases.
What is the design value of short circuit ration of generator?
short circuit ratio is the ratio of field current to open short circuit voltage n the open circuit current. its value for thermal is less than hydro type.
How short is a shortcircuit?
A short circuit is so short that all the current in the entire network prefers to pass through it! Actually, whenever in a network/circuit there are two parallel paths for the current to flow, the current chooses the path of least impedance. As such, a circuit with no impedance of any sort is called a short circuit cuz the entire current passes through it.
What is the rated short circuit capacity of the miniature circuit breaker used?
Breaking Current: The r.m.s value of short circuit current at the instant of contact separation.
Can a short circuit cause low voltage?
Most likely a short circuit will cause no voltage. Due to the high current on a short circuit fault the over current protection of the circuit will trip. This will cut the voltage supply off completely.
