What type of resistance do conductors have?
Conductors have a (low) Electrical resistance.
What is resistivity and what factor does it depend?
Electrical resistivity (also known as resistivity, specific electrical resistance, or volume resistivity) quantifies how strongly a given material opposes the flow of electric current. A low resistivity indicates a material that readily allows the movement of electric charge. Resistivity is commonly represented by the Greek letter ρ (rho). The SI unit of electrical resistivity is theohm⋅metre (Ω⋅m)It defined as resistance offerde by a unit length and cross section area conductor.It depends on material used.it depends on relexation time and temperature.
Is resistivity of a good conductor high or low?
It is Low
Good conductors have a high resistance or low?
Good conductors have low resistance
What the best conductors and insulators?
Most Metals are the best conductors. Like, silver. The best insulators are plastic, like glass. These materials are some of the best conductors/insulators because of their ability/inability to conduct electric current. Electric current is the flow of electric charge through a medium. Insulators have a high resistance and do not allow electrons to flow easily through them. Conductors have a low resistance allowing electrons to flow freely. In order to say which is the best or worst conductor you can check a resistivity table(typically measured in ohms). Be careful to look at the temperature of the material because that can change the resistivity.
What type of resistance do conductors have?
Conductors have a (low) Electrical resistance.
What do all conductors of electricity have in common?
The best conductors of electricity have that they are all metals in common.
Why is copper wire the best known conductor?
The best electrical conductor known is silver, not copper. Electrical resistivity of silver: 1,59.10-8 ohm.m Electrical resistivity of copper: 1,68.10-8 ohm.m A good electrical conductor has a very low electrical resistivity and a high electrical conductivity (the same principles for the thermal conductivity).
What is it called if a material conducts easily?
It is said to have a low resistance:A low thermal resistivity for heatA low electrical resistivity for electricityA low opacity or high transparicyfor light.

Why is copper used for electricial wiring?
Because copper has a very low electrical resistivity of 16.78 nΩ·m, meaning it's easier for electricity to pass through it. For comparison, nickel has a resistivity of 69.3 nΩ·m and iron's resistivity is 96.1 nΩ·m.
What are the electrical properties?
good conductors of heat bad insulators low resistence high conductivity
Why do alkaline earths have low resistivity?
They are highly reactive. They are in the s block.
Is lead conductor?
Lead has high resistivity of current. So , lead is not conduct current. But lead has low resistivity of heat and it conduct heat..
Is resistivity of a good conductor high or low?
It is Low
What type of material allows a charge to move freely through it?
A material through which an electric current flows easily is called an electrical conductor. Many metals, especially silver and copper, are excellent electrical conductors.
How does copper transport electricity?
Copper is one of the best electrical conductors because it has very low electronegativity and ionization energies which are in play to facilitate electrical conductivity.
