RESISTIVITY explain it in 100 words
Answers
Answer:
Resistivity is a measure of the resistance of a given size of a specific material to electrical conduction.
Resistivity may also be referred to as the specific electrical resistance, or volume resistivity, although these terms are less widely used.
Although materials resist the flow of electrical current, some are better at conducting it than others.The resistivity is a figure that enables comparisons of the way in which different materials allow or resist current flow.
To enable resistivity figures to be meaningful, specific units are used for resistivity, and there are formulas for calculating it and relating it to the resistance in Ohms for a given size of material.
Materials that conduct electrical current easily are called conductors and have a low resistivity. Those that do not conduct electricity easily are called insulators and these materials have a high resistivity.
The resistivity of different materials plays a major role in selecting the materials used for electrical wire, within many electronic components including resistors, integrated circuits and many more.
