What else can I help you with?
Does a short copper wire have more resistance then a long one?
No, resistance depends on the material, cross-sectional area, and temperature of the wire. A shorter wire will have less resistance compared to a longer wire since it offers less opposition to the flow of electrical current.
Does a long wire have more resistance than a short wire?
Yes, a long wire typically has more resistance than a short wire due to increased electron collision and higher impedance over a longer distance. This is because resistance is directly proportional to the length of the wire.
Is electric resistance greater in a short fat wire of a long thin wire?
Electric resistance is greater in a long thin wire compared to a short fat wire, due to the higher resistance associated with longer wires and thinner cross-sectional areas. Resistance is determined by the material's properties and dimensions, with length and cross-sectional area being key factors affecting resistance.
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.
How can resistance be reduced in wire?
Resistance in a wire can be reduced by using a thicker wire or a material with lower resistivity, like copper. Keeping the wire short and straight also helps reduce resistance. Additionally, ensuring good connections and minimizing temperature fluctuations can further decrease resistance.

What happens if you shorten the resistance wire in a circuit?
It shortens
What happens to the resistance of wire if it is made thinner?
woltz
Does long wire have a lower or higher resistance than short wire?
A long piece of wire will have more resistance in it than a shorter one of the same material.
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.
Does a long wire have more resistance than a short wire?
Yes, a long wire typically has more resistance than a short wire due to increased electron collision and higher impedance over a longer distance. This is because resistance is directly proportional to the length of the wire.

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 happens to the resistance of copper wire as the temperature of the wire increases?
The resistance of copper wire increases as the temperature of the wire increases. This is due to the increase in collisions between free electrons and atoms in the wire, which hinders the flow of electricity.
What happens to the resistance of a filament if it is replaced by a shorter wire?
If a filament is replaced by a shorter wire, the resistance will decrease. Resistance is directly proportional to the length of the wire, so a shorter wire will have lower resistance. This is because there is less material for the electrons to travel through, resulting in less opposition to their flow.
