Define the term resistivity
Answers
Answer:
resistivity is the fundamental property and requisite shows how strongly a material opposes flow of current.
p =(R.A) / L
Explanation:
ability of a material to resist the flow of electricity through it.
Example :- I have 2 copper materials, one is strip and other one is copper wire then resistivity is same for both.
Answer:
It is the physical property of any particular substance through any cross sectional area.
It is measured in ohm meter.
It is directly proportional to the nature and material of wire.
It is used for measuring quality of calcareous soil.
Bad conductor of heat and electricity has high resistivity.
Resistivity of a metallic conductor increased with increased in temperature.
ρ = (R × A)/ L
R stands for Resistance, L = Length, A = Cross-sectional area
