The circuit resistance is likely to gradually drop and in such case it will cause the circuit to burn down.

Why do you mean by 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.


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.


When there is almost no resistance in a circuit what is it called?

This is what is known as a "short circuit".


What happens to the total resistance in a parallel circuit with a short?

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.


Why don't AC input wires to a transformer just short circuit?

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.


What is the value of the resistance of an short circuit?

ohms


Why short circuit has very low resistancs?

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.


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.


The value of resistance of an short 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.


Is the current pass through parallel short resistance?

no.because current always try to flow trough low resistance path.as short circuit has low resistance current pass trough short circuit


What happens if a circuit has no resistance?

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.


What are the approximations of open circuit and short circuit tests?

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.
