Electrical Conductivity
What is Electrical Conductivity?
Electrical conductivity is a measure of a material’s ability to conduct an electric current. It describes how easily electricity can flow through a substance.
What is SI Unit of Electrical Conductivity?
The SI unit for electrical conductivity is siemens per meter (S/m).
What is the Formula of Electrical Conductivity?
The following is the formula for electrical conductivity : σ = 1/ρ = l/AR, where ρ is the resistivity, R is the resistance, l is the length of the conductor and A is area.
What are the Three Types of materials based on Electrical Conductivity?
Materials can be classified into three types based on their electrical conductivity:
- Conductors that have high electrical conductivity.
- Insulators that have low electrical conductivity.
- Semiconductors have an intermediate level of electrical conductivity between conductors and insulators.
How is Electrical Conductivity measured?
Electrical conductivity can be measured using conductivity meter and probe
Electrical Conductivity
Electrical conductivity is a fundamental property that measures a material’s ability to conduct electric current. It varies among materials and is influenced by factors such as temperature, material composition, impurities, and pressure. Electrical conductivity is typically measured in siemens per meter (S/m).
Electrical conductivity finds applications in electronics, power transmission, material science, environmental science, geology, biomedical fields, and more. In this article, we learn about electrical conductivity in detail.
