What else can I help you with?
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.
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
When a dead short occur what happens to circuit resistance?
The circuit resistance is likely to gradually drop and in such case it will cause the circuit to burn down.
What is an electric circuit with little or no resistance?
A: As current approaches infinity on a device it is known as a current source.
What is the difference between an short circuit and a closed circuit?
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
What is the value of the resistance of an short circuit?
ohms
Can inserting a resistor in a circuit have an effect similar to an short circuit?
It creates an extra load to the circuit if placed parallel to other circuits. this load approaches the equivalent of a short circuit as the resistance value placed there reduces.
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.
Why resistance is high during short circuiting?
Resistance of a short circuit is actually very low, ideally it is 0 Ohms. In practice the resistance of a short circuit will be equal to whatever the resistance of the short circuited wires is, which is typically very small. So if you substitute very small resistance value R into Ohm's Law(I = V/R), you will get a very high current flowing. Where V=voltage,I=current.
When there is almost no resistance in a circuit what is it called?
This is what is known as a "short circuit".
How can I test for a short circuit in a circuit?
To test for a short circuit in a circuit, you can use a multimeter set to measure resistance. Disconnect the power source, then place the multimeter probes at different points in the circuit. If the resistance reading is very low or zero, it indicates a short circuit.
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.
Why ammeter works as short circuited in circuit?
The ammeter is basically a Galvanometer with a small resistance to parallel with it. As we know that, if we connect two resistances in parallel, then the equivalent resistance is equal to the the value which is less than the value of lowest resistance connected in parallel. suppose if we connect 1 ohm & 0.1 ohm in parallel, then the equivalent of it will be 0.0909 ohm (less than 0.1 ohm). means in parallel circuit the equivalent resistance become smaller. as like this a small parallel resistance across galvanometer decreases the value of the value of resistance of it. since it gets very small value, so it connected in series to measure the value of current in the circuit. due to very low resistance, it drops very low voltage on it ( upto can be negligible) so we assume that it works like a short circuit.
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.
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
When a dead short occur what happens to circuit resistance?
The circuit resistance is likely to gradually drop and in such case it will cause the circuit to burn down.
