Resistivity is a constant for any particular material, and independent of that material's physical dimensions or shape. However, it does vary with temperature which is why resistivity is always quoted at a particular temperature. Variations in resistivity due to temperature change is the reason that the resistance of a material varies with temperature. In SI, resistivity is expressed in ohm metres.

What property of graphite makes it suitable for use as electrodes?
The electrical conductivity
Which property of solder makes it suitable for welding electrical wires?
It has a low melting point but has excellent electrical conductivity.
Why copper electrode does not melt while steel melts in spot welding?
Copper has a higher melting point than steel, so it does not melt during spot welding. Additionally, copper has higher thermal conductivity, which allows it to distribute heat more efficiently and prevent it from concentrating in one spot. This combination of a higher melting point and better heat dissipation makes copper electrodes suitable for spot welding applications.
What causes an increase in the rate of a chemical reaction between 2 liquids?
Increasing the temperature will increase the reaction rate, as will finding a suitable catalyst.
Is salt solution is a good conductor of electricity?
Salt in solution improves conductivity but it does not make a conductor as good as a metal. Deionized water has an electrical conductivity of 5,5 * 10-6 [S*m-1] but Seawater (3,5% salt in solution) has a conductivity of 4,8 [S*m-1] compared to Sliver with a conductivity of 6,3 * 107 [S*m-1] (the best known at room temperature)

Why is pure water not suitable to sue in a Hoffmann apparatus for the electrolysis of water?
Extremely pure water (Kolrausch water) has a very poor electrical conductivity.

Why is Gold Mined?
For its monetary value making it suitable for bullion (currency references), jewellery and gilding, its chemically-inert nature and high conductivity make it suitable for various applications in electronic and medical components.
What are TWO physical properties of copper that make it suitable for electrical wiring?
Like gold and silver, copper is malleable, that is, it can be bent and shaped without cracking, when either hot or cold. It can be rolled into sheets as thin as 1/500 of an inch.Copper also is ductile, meaning it can be drawn out into thin wire. A copper bar four inches thick can be heated, rolled, then drawn into a round wire so thin that it is thinner than a strand of human hair.Here are some more physical properties, which can describe copper (not quantified, but a list of properties that can be quantified): hardnes, ductile. Electrical conductivity. Thermal Conductivity. Melting point, density. Others which don't really have a quantity: Lustre / shinyness, color.
What makes ceramics suitable to make tiles?
its useful for electrical wiring because that is the way it is
Which type of motor suitable for the drive of an electrical powered vehicle?
dc series motor
What decimal place is uncertainty in measurement of water?
This is not actually a question, and doesn't parse. Water an be subjected to many measurements, with a few common types being volume, temperature, electrical conductivity, and mass. Thus, a suitable response is "Has anyone really been far even as decided to use even go want to do look more like?"
Which heat treatment process is suitable to increase the ductility in steel?
how to increse the Tensil more than 1100 for Crmo4
How electrical circuit operate?
The topic is not suitable to be discussed in this forum. I suggest reading a box or taking a class.
How is copper that is suitable for making electrical wires produced?
Electrolysis extraction from Copper Ore.PS: Answer may be incorrect.
