Concept explainers

Resistivity

Resistivity is a characteristic property of the conductor’s material that measures the extent to which the material opposes the flow of current. It is denoted by the Greek letter “rho”. Electrical resistivity, also known as specific resistance, depends on the nature of the material of the conductor and is unaffected by its dimensions.

Discussion: Ohm's Law describes the relationship between the resistance (R) of a wire, the roltage drop across it (V), and current through it (D): V = RI (1) Applying a known current to a wire and measuring the voltage across it will lt you determine the resistance of the wire by solving equation 1: R =, (2) The resistance of a partieular element depends on its geometry, the resistivity and the temperature. Resistivity is the tendency of the material to behave as a resistor and is an inherent property of a material, in the same sense that density or thermal expansion are inherent properties. Materials with lower resistivity, like copper, are good conductors of electricity and widely used in eireuit components while those with larger resistivity, like rubber, are used as insulators. For a wire with length (L), cross-sectional area (A), and made from a material with resistiity (p) the resistance (R) will be given by the following equation: R= L (3) In case that the geometry (length and…
