Resistance is the ability of the substance to resist the flow of electrons through it.
Resistance is directly dependent on the length of the conductor.
Area of any conducter is inversely related to its resistance.

Short circuits are dangerous because?
electricity always "wants" to take the easiest route, this is the route with the least resistance, this is why an insulator does not conduct electricity, it takes to much force for the electricity to travel through. a short circuit is when the easiest route is the wrong route i.e. the body of a lamp rather than the wiring of the lamp. the danger of a short circuit is dependent on the voltage and current of the electricity.
The rate at which charges move through a conductor is called?
there is no name for the rate of charge transfer, but its inverse is resistance: resistance is how much charge is resisted, so a low resistance material will have a larger rate of change of charge than a high resistance material.
How is resistance useful?
It keeps the electron flow in check. Wthout resistance, current flow, (or amperage), would be too excessive and hard to control. Think what would happen if you placed a metal wire from one post of a car battery to the other post (a direct short with no resistance). The wire would melt and overheat and also possibly damage the battery from excessive amperage flow.
Which has a higher resistance insulators or conductors?
No, the resistance of an insulator is very high.
How much resistance do your body have?
You can not find a set amount of electrical resistance because your body is made of many different materials and the amount varies with time ex: your body may, hypothetically, conduct more current if it is better hydrated
What happens to resistance of the wire if the wire is short?
Short wire has less resistance Long wire has more resistance Thick wire has less resistance Thin wire has more resistance
What will make an amp surge to protect mode in a car?
a short or too much resistance thus heat
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 is the meaning of short circuit conductor?
A short circuit conductor is just a conductor in an unexpected location, often with much lower resistance that is expected for the normal load.
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.
Will a short thick metal wire have better resistance compared to a long narrow metal wire?
"Better" depends on how much resistance you need for your circuit design.A short thick wire will have less resistance than a long thin wire of the same substance.Whether that's better or worse depends on how you plan to use the wire.
What is the value of the resistance of an short circuit?
ohms
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.
Does a short copper wire have more resistance then a long one?
No. Other things being equal, a long wire has more resistance than a short wire.
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 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.
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.
