Define resistance, resistivity, conductance, conductivity of conductor
Answers
Answer:
Electrical resistivity (also called specific electrical resistance or volume 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.
Answer:
RESISTANCE
Resistance is defined as a ratio of the voltage applied to the electric current.
R(resistance)=voltage/Current i.e. R=V/I
RESISTIVITY
Resistivity is the measure of resistance of specific material.
roh=R×A/L
CONDUCTANCE
the degree to which an object conducts electricity, calculated as the ratio of the current which flows to the potential difference present.
It is the reciprocal of resistance i.e. I÷V
CONDUCITIVITY
Conducitivity defines a materials ability to conduct electricity.
Conducitivity is the reciprocal of resistivity
Conducitivity =1/Roh
