Another name for a circuit with low resistance and high current is a short circuit. It is dangerous because, if you have sufficient energy in the power source, you can damage components and/or cause fires.
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.
to determine the comparison of resistance value of both forward and reverse diode . The more the resistance the lower the current , the lower the resistance the higher the current . When reverse bias , the resistance is high and it acts in open circuit and the reverse current is very small that can be neglected . When forward bias , the resistance is low and it acts as short circuit and the forward current is increasing as the voltage supply is higher .
The purpose of a voltmeter is to indicate the potential difference between two points in a circuit.When a voltmeter is connected across a circuit, it shunts the circuit. If the voltmeter has a low resistance,it will draw a substantial amount of current. This action lowers the effective resistance of the circuit andchanges the voltage reading.
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
The voltmeter has an internal resistance, which should be as high as possible. As this resistance draws current from the circuit under test, it will affect circuit operation. This is more pronounced in a high impedance circuit because the current drawn flows through higher resistances.

Yes
The current flowing in a circuit is said to be very small when it is in the range of microamperes (10^-6 A) or even lower. This low current can be indicative of high resistance or very low power consumption in the circuit.
Because it is a metal so has lots of free electrons which when connected to a circuit detach from the atoms and move around the circuit. This produces a high current, so resistance will be low as current is high.
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.
A rheostat is a variable resistor that can increase or decrease the resistance in a circuit. By increasing the resistance in the circuit, the rheostat limits the flow of current, causing it to become higher in the parts of the circuit where the resistance is lower.
If one branch of a parallel circuit has high resistance, it will draw less current compared to branches with lower resistance. This means that most of the total current will flow through the lower-resistance branches. Consequently, the voltage across all branches remains the same, but the overall current provided by the power source will be affected, potentially resulting in decreased total current in the 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.
When there is corrosion in a circuit, it results in lower current flow. This is because corrosion actually causes resistance.
A high current flows through a short circuit even if there is no voltage change because the resistance across the short circuit is zero.
Of the three choices, capacitance does not limit current flow in an AC circuit.
