no.because current always try to flow trough low resistance path.as short circuit has low resistance current pass trough short circuit
The total resistance of a set of resistors in parallel is found by adding up the reciprocals of the resistance values, and then taking the reciprocal of the total. By removing a resistor the total current will lower. If you short out the parallel circuit as suggested it will take out the fuse that should be protecting the circuit.AnswerShorting-out a resistor in a parallel circuit, will act to short out the entire circuit, therefore, significantly increasing, not lowering, the current! And, as the previous answer indicates, this short-circuit current will operate any protective devices, such as a fuse.In a parallel circuit current does not lower but it will be increase if shorting-out one resistor in the two resistor parallel circuit, the circuit will become very low resistive and the larger current will flow through the short path.
If at battery,parallel circuit shorts then equivalent resistance of circuit becomes approximately 0 Ohms,and therefore as current follows low resistance path infinite amount of current due to low resistance will flow through the wire so,entire parallel circuit will short out,but wire will burn and battery may get damaged.

In case of series winding total line current is flow through it.line current is very very high.so,to minimize the drop the winding made as low turns and low gauge.hence the resistance is low.in case of shunt winding high resistance winding is used otherwise short circuit the parallel winding.for that winding is made as heavy turns and heavy gauge.
Take the internal series resistance of the voltage source and make it the internal parallel resistance of the current source. Then compute using Ohm's law the current of the current source to be equal to the maximum current the original voltage source could supply a short circuit load. Note: the two sources are equivalent.
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.
A current checks less resistance path to flow. When one of parallel branches is shorted, it becomes have less resistance and whole the current will flow through it, means current before parallel branches and current after parallel branches becomes same, and all branches become short.

For protection.. Since the current prefer the short cut ..
Connecting an ammeter in parallel with a circuit element is hazardous. Because of its negligible resistance, it is equivalent to applying a short circuit across that element, and the resulting current through the ammeter may severely damage the instrument if it is not fused.
An ammeter has low resistance (ideally no resistance) because it is placed in series with other circuit elements to detect how much current is flowing. If it is placed in parallel with a component it will short-circuit it. That is a bad thing.
It depends on weather it is in a parallel or series circuit. In parallel the entire circuit it is in parallel with is shorted out. In series the total resistance decreases by the amount of the resistor that shorted out. Resistors usually open or change value with use.
A high current flows through a short circuit even if there is no voltage change because the resistance across the short circuit is zero.
decrease to half of its original value
Theoretically yes. However, there is always resistance through joints,components and trace impurities in wires. A dead short is only a dead short for an instant at a fixed temperature. As heat rises so does resistance. Consequently current falls. also, resistance of zero would violate the laws of thermodynamics, because it would imply zero entropy

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.
