The circuit resistance is likely to gradually drop and in such case it will cause the circuit to burn down.
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.
The value of resistance when there is a short circuit varies depending on the nature of the fault, but it could be fractionally above zero or higher.
no.because current always try to flow trough low resistance path.as short circuit has low resistance current pass trough short circuit
A: As current approaches infinity on a device it is known as a current source.
You know there is a differnce. The dynamic short circuit is dynamic and the static short circuit is static. It's common sense really.dyanamic means when due to some external source theresistance becomes zero ,can be through anythin due to high supply of current or anything,the current in that circiut becomes infinite and that result s in short circuiting. Static short circuit means when through the different changes in the voltage makes the resistance zero and current infinite , V = I/R WHERE R= 0 AND CURRENT BECOMES INFINIT AND THAT RESULT IN A SHORT CIRCUIT
A short circuit is a low resistance connection established by an accidental touching between a line supply and a grounded object in an electric circuit. The current will flow through the low resistance point, bypassing the rest of the circuit. When this happens the circuits over current device should open the 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.
This is what is known as a "short circuit".
In case of parallel circuit the effective resistance is given by Reff = R1*R2*R3 /(R1R2 +R2R3 +R3R1) As short circuit takes place then anyone R1,R2,R3 becomes zero. Hence Reff becomes zero.
The resistance of the winding in the primary of a transformer constitutes a load. As long as there is resistance then there is no short circuit. A short circuit is considered no resistance which develops an instantaneous high current. That is why fuses and breakers are inserted into the circuit to open the high current flow under a short circuit condition.
ohms
A short circuit is defined: An unintentional connection of low resistance or impedance in a circuit such that excessive and often damaging current flows in it (from Wiktionary.org) Why a short circuit has very low resistance is very simple: because that's how "short circuit" is defined.
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.
The value of resistance when there is a short circuit varies depending on the nature of the fault, but it could be fractionally above zero or higher.

Then the voltage in will equal the voltage out. The purpose of a resistor is to reduce the amount of electrical flow of current. You 'short out' the supply and blow a fuse/circuit breaker.
Firstly turn of the power before this test...Using a resistance or continuity tester you should get the following results:Short circuit: Very low resistance (nearly 0 ohms) or the bell will ring.Open circuit: Very high resistance (Somewhere in the range of Mega ohms) or the bell will not ring.The reason for this is because and open circuit has a gap in it (which has high resistance).The short circuit has wires that are crossed and so has a really low resistance.
