Question

Define conductivity. What are conductors of electricity? Explain with examples.​

Answer 1

Answer:

$\huge\bold\red{Answer}$

• 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.

Answer 2

Answer:

Electrical conductivity is the measure of the amount of electrical current a material can carry or its ability to carry a current. Copper, Brass, Steel,Gold, and Aluminum are good conductors of electricity....
