Rezistivitatea
Rezistivitatea, also known as electrical resistivity, is an intrinsic property of a material that quantifies how strongly that material opposes the flow of electric current. It is a fundamental characteristic that is independent of the object's shape or size, unlike electrical resistance. The symbol commonly used for resistivity is the Greek letter rho (ρ).
The unit of resistivity in the International System of Units (SI) is the ohm-meter (Ω⋅m). A low
Resistivity is related to electrical resistance (R) by the formula R = ρ(L/A), where L is the length
