define conductivity
Answers
Answer:
Conductivity defines a material's ability to conduct electricity. Electric current can flow easily through a material with high conductivity. Conductivity is measured in siemens per meter and is often represented using the Greek letter σ.
Answer:
Conductivity defines a material's ability to conduct electricity. Electric current can flow easily through a material with high conductivity. Conductivity is measured in siemens per meter and is often represented using the Greek letter σ. A material such as metal has a high conductivity, while rubber has a very low conductivity. A semiconductor's conductivity is intermediate. Factors such as temperature have a large effect on conductivity. Resistivity is the reciprocal of conductivity so that a material with high conductivity has low resistivity, and a material with high resistance is, by definition, a poor conductor.
