For a 4 AWG copper wire in a three-conductor setup, the recommended gauge is typically 10 AWG with three conductors for proper electrical conductivity and safety.
copper is the best electrical conductivity
from wiedemann franz law we know that thermal conductivity/electrical conductivity=constant that is sigma inv. proportional to k thus a material having large electrical conductivity has low thermal conductivity and moreover we know R=pL/A p=RA/L 1/P=L/RA i.e lower area means greater conductivity(electrical) and lower thermal conductivity
Thermal conductivity measures a material's ability to transfer heat energy, while electrical conductivity measures its ability to transfer electrical energy. Materials with high thermal conductivity are good conductors of heat, whereas those with high electrical conductivity are good conductors of electricity.
Yes, substances with good electrical conductivity typically also conduct heat well. This is because the movement of electrons that allows for good electrical conductivity also facilitates the transfer of thermal energy. Materials like metals, which are good conductors of electricity, are also good conductors of heat.
Normally, materials which are good conductors of electricity are also good conductors of heat. This is because both electrical conductivity and heat conductivity is enhanced by mobile electrons, thus making metals both good electrical conductors and good heat conductors. However, I do not know if there might be an exception...
good conductors of heat bad insulators low resistence high conductivity
In electrical conductors, electrons can move freely, allowing for the transfer of electrical energy. This results in conductors having high electrical conductivity. In contrast, in insulators, electrons are tightly bound to their atoms and cannot move easily, leading to low electrical conductivity. Insulators have high resistance to the flow of electricity due to this lack of electron mobility.
Most substances fall into two categories - conductors and insulators. Conductors are those which electricity can pass through relatively easily. Metals are the usual example, but other substances such as graphite and polar liquids such as water are also good conductors. Insulators are poor conductors: those that electricity cannot pass through easily. Most plastics are insulators. Some substances fall in between: these are semiconductors, which allow electricity through in some instances, but not in others. This property makes them very useful in electronics. Some substances can be such good conductors that, under some circumstances, they can allow electricity to pass through them with no resistance at all. These are called superconductors.
Copper, silver, and gold are three of the best electrical conductors due to their high conductivity and low resistance. These materials are commonly used in electrical wiring and electronics where efficient transmission of electricity is important.
no all the conductors do not have the same electrical conductivity as copper is a good conductor and silver is the best but it is costly.
No, high density materials are not necessarily good electric conductors. Electrical conductivity is determined by the availability of free electrons in a material, not its density. Typically, metals with high electron mobility, such as copper and aluminum, are good conductors of electricity.
The recommended wire size for aluminum conductors to handle a 100 amp electrical load is typically 2 AWG (American Wire Gauge).
