What has a lower resistance a long thin iron wire at high temp or a short thick copper wire at low temp?

A short thick copper wire at low temperature would have lower resistance compared to a long thin iron wire at high temperature. This is because resistance is inversely proportional to cross-sectional area and directly proportional to temperature and length of the wire. The short thick copper wire has a larger cross-sectional area, which results in lower resistance.


Which wire would have the lowest resistance a long thin iron wire at a high temperature or a short thick copper wire at a low temperature?

The short thick copper wire at a low temperature would have the lowest resistance. Copper has lower electrical resistance than iron, and a shorter, thicker wire has lower resistance compared to a long thin wire, regardless of the temperature.


What wire will allow high current to pass through without getting hot?

A wire with low resistance. To obtain the lowest resistance, the wire must be -- thick -- a good conductor; silver, copper, etc. -- cold


Items that use low resistance wire?

Ni chrome is a low resistance wire used in heaters and toasters.


Why copper strips are used in meter bridge wire?

Copper strips are used in a meter bridge wire due to their excellent conductivity, which allows for accurate measurement of resistance in the wire. The low resistance of copper helps minimize any potential measurement errors caused by the resistance of the connecting wires.


What wire connection better high or low resistance?

Usually low resistance is better.


Why is thick copper wire good for carrying a current?

Oh, dude, thick copper wire is like the superhero of conducting electricity. It's all about that low resistance life - the thicker the wire, the less resistance it has, which means more current can flow through without getting all tangled up. So yeah, thick copper wire is like the VIP lane for electrons, just breezing through without breaking a sweat.


Does thin wires have high or low resistance?

Thin wires have high resistance because they offer more obstruction to the flow of electrical current compared to thicker wires. This increased obstruction results in higher resistance, as described by Ohm's law.


What is a fuse wire characterized by?

Low resistance and low melting point by "justquikr.com"


Does a good conductor has a high resistance?

No, a good conductor has a low resistance.


What resistance of a connecting wire is less than the resistance of a resistor?

The resistance of a connecting wire that is less than the resistance of a resistor would depend on the materials and dimensions of the wire and resistor. Generally, most connecting wires have very low resistance compared to resistors. Copper wires, for example, have low resistance and are commonly used for connecting circuits.


What would happen if a wire is too narrow and the current is too strong?

Too narrow for what ? Too strong for what ? A narrower wire has higher resistance. The power (heat) dissipated by the wire is . . . (current)2 x (resistance). -- If the resistance is low and the current is low, the wire dissipates very little heat. You don't notice it, it doesn't start a fire, and the circuit that the wire is part of works fine. -- If the resistance or the current is somewhat higher, the wire dissipates more heat, and it gets warm. -- If the (current2 x resistance) is still higher, then the wire dissipates a lot of heat. It can be used in a toaster, a hair-dryer, an electric coffee percolator, or an electric baseboard heater. -- If the wire is inside a container from which the air has been removed, and the (current2 x resistance) is high enough to cause a short section of the wire to dissipate a fair amount of power, then you've got yourself a light-bulb. -- If the (current2 x resistance) is high enough to cause the wire to generate so much heat that it melts, then you have a fuse, which just blew.
