What is Resistivity?
Open in App
Solution
Resistivity:
A material's electrical resistivity is a measure of how strongly it opposes the flow of current.
The ohm meter (m) is the SI unit of electrical resistivity.
The Greek letter rho is commonly used to represent it.
Conductors are materials that easily conduct current and have a low resistivity.
Insulators are those who do not conduct electricity and have a high resistivity.
The magnitude of the electric field across it that produces a specific current density is used to define resistivity.
