Difference between resistence and resistivity?

Question

Answer

1--Resistance is referred as the tendency of the conduct to oppose the flow of current flowing in it. In other words , The ratio of potential difference of ends of the conductor and the current flowing in it is called Resistance.It is denoted by R.Therefore , R = V / I Unit of resistance is OHM.2--Resistivity of a conductor is dependent upon nature of conductor , it's length and area of cross section. Alternatively , The Resistance offered by a cube of some substance having side of 1 metre , when current flows perpendicular to the opposite faces , is called it's resistivity.It is denoted by Rho (p).Therefore, rho (p) = R ×(area of cross section/length ) Si Unit -- ohm•metre

Answer

Resistance is property of a material which oppose the flow of current while resistivity is a resistance of specific length and area. it is also known as specific resistance

Answer

R = row × L/ A is resistance or row is constant called resistivity

Answer

Understanding Resistance
Resistance is a measure of how much an object opposes the flow of electric current. It is influenced by several factors, including the material's properties, its dimensions, and temperature.
Key Characteristics of Resistance:

Unit: Measured in ohms (Ω).
Depends on Geometry: Resistance increases with the length of the conductor and decreases with its cross-sectional area.
Material Dependent: Different materials have varying abilities to conduct electricity; for example, copper has low resistance, while rubber has high resistance.

Understanding Resistivity
Resistivity, on the other hand, is an intrinsic property of a material that quantifies how strongly it resists the flow of electric current, regardless of its shape or size.
Key Characteristics of Resistivity:

Unit: Measured in ohm-meters (Ω·m).
Material Property: Resistivity is a constant for a given material at a specific temperature.
Temperature Dependence: Resistivity can change with temperature; for most conductors, it increases with temperature, while for semiconductors, it can decrease.

Summary of Differences

Definition: Resistance is a measure of opposition to current in a specific object; resistivity is a property of the material itself.
Dependence: Resistance depends on the object's size and shape; resistivity is independent of these factors.
Applications: Resistance is crucial for circuit design; resistivity is essential for material selection in electrical applications.
