#### What is Rho resistivity?

A low**resistivity**indicates a material that readily allows the flow of electric current.**Resistivity**is commonly represented by the Greek letter ρ (**rho**). The SI unit of electrical**resistivity**is the ohm-metre (Ω⋅m).#### Which metal is the best conductor of electricity?

Silver#### What does the resistivity of a material depend on?

The resistivity of a material is the resistance of a wire of that material of unit length and unit cross-sectional area. The unit for resistivity is the ohm-metre. The resistivity of a material depends on its nature and the**temperature**of the conductor, but not on its shape and size.

### What is resistivity of a material?

The electrical

**resistivity of a material**is also known as its specific electrical**resistance**. It is a measure of how strongly a**material**opposes the flow of electric current. A definition of**resistivity**is the electrical**resistance**per unit length and per unit of cross-sectional area.#### What is the ohm?

The**ohm**is defined as an electrical resistance between two points of a conductor when a constant potential difference of**one**volt, applied to these points, produces in the conductor a current of**one**ampere, the conductor not being the seat of any electromotive force.#### What is resistivity Class 10?

The**resistivity**of a material is the resistance of a wire of that material of unit length and unit cross-sectional area. The unit for**resistivity**is the ohm-metre. The**resistivity**of a material depends on its nature and the temperature of the conductor, but not on its shape and size.#### What is the resistivity of copper wire?

### What is the resistance of gold?

As the graph shows, the resistivity of a substance is very much dependent on temperature. For most conductors, resistivity increases with rising temperature. At 20 °C, the resistivity of gold is

**approximately 2.44 × 10**^{−}**-m and steadily rises with increasing temperature.**^{8}ohm#### What does the resistivity of a material depend on?

The resistivity of a material is the resistance of a wire of that material of unit length and unit cross-sectional area. The unit for resistivity is the ohm-metre. The resistivity of a material depends on its nature and the**temperature**of the conductor, but not on its shape and size.#### What is the specific resistance of gold?

As the graph shows, the resistivity of a substance is very much dependent on temperature. For most conductors, resistivity increases with rising temperature. At 20 °C, the resistivity of gold is**approximately 2.44**× 10^{−}-m and steadily rises with increasing temperature.^{8}ohm#### Why Copper is a good conductor of electricity?

The electrons can move freely through the metal. For this reason, they are known as free electrons. They are also known as conduction electrons, because they help**copper**to be a**good conductor**of heat and electricity.
