Define the term resistivity of material and rastance
Answers
Answer:
resistance is the property of a material by virtue of which it opposes the flow of charges through it
Electrical resistivity and its inverse, electrical conductivity, is a fundamental property of a material that quantifies how strongly it resists or conducts electric current. A low resistivity indicates a material that readily allows electric current. Resistivity is commonly represented by the Greek letter ρ.
SI units: Siemens per meter (Electrical conductivity), Ohm meter (Electrical resistivity)
Resistance is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω). Ohms are named after Georg Simon Ohm (1784-1854), a German physicist who studied the relationship between voltage, current and resistance.
