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.

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.
What happens to resistance of the wire if the wire is short?
If the wire is short, its resistance will likely decrease. A shorter wire has less length for electrons to travel through, resulting in lower resistance according to the formula R = ρL/A, where R is resistance, ρ is resistivity, L is length, and A is cross-sectional area.
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 do thick wires resist electricity?
Thick wires have lower resistance to electricity compared to thin wires because they have more surface area for the current to flow through. This lower resistance allows for more efficient transmission of electricity with less energy loss in the form of heat.
Compared to thin wires electrical resistance in thick wires are?
Lower in thick wires due to their larger cross-sectional area, which allows for more space for electrons to flow and reduces the resistance. Thicker wires also have less electrical resistance because they experience less heat loss, making them more efficient for carrying electrical currents over greater distances.
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.
Why is thick copper wire good for carrying current?
Thick copper wire is good for carrying current because it has a lower electrical resistance compared to thinner wires. Lower resistance results in less energy loss through heat generation, making thick copper wire more efficient for transmitting large amounts of current without overheating.

Is copper used in thick layers?
Copper is commonly used in thick layers for applications requiring high conductivity and durability, such as in electronics, electrical wiring, and power distribution. Thick copper layers are particularly important for ensuring low electrical resistance and improving heat dissipation in these applications.
What do thick wires resist electricity?
Thick wires have lower resistance to electricity compared to thin wires because they have more surface area for the current to flow through. This lower resistance allows for more efficient transmission of electricity with less energy loss in the form of heat.
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.
How thick is the copper used in Van Earp style copper lamps?
Its around .030 thick.
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
Why does resistance increase in thinner wires?
A thick wire has its cross section area more than that of the thin one .Since the resistance of a material is inversely proportional to its resistance, resistance of thick wire is less compared to.[as cross section area increases the no electrons drifted increases].this applies only to OHMICdevices.
Compared to thin wires electrical resistance in thick wires are?
Lower in thick wires due to their larger cross-sectional area, which allows for more space for electrons to flow and reduces the resistance. Thicker wires also have less electrical resistance because they experience less heat loss, making them more efficient for carrying electrical currents over greater distances.
