define resistance and resistivity of cond
Answers
° resistance opposes the flow of charge
R=V/I
° R is directly propotional to its length
° R is inversely proportional to its area of crossection
° R is directly proportional to resistivity
RESISTIVITY
it is the characteristic property of the substance ,it is independent of its shape and size of a body
° its SI unit is ohm * m
Answer:
Explanation:
Resistance the the property of the conductor which can oppose the flow of current in conductor .
Resistance of conductor is depend upon
● Lengthy
● Area of cross section
● Temperature
● Material of conductor
Resistivity It is the resistance of a conductor whose length is one meter and area of cross section is one sq-meter.
Resistivity of conductor is depend upon
● Temperature
● Material of conductor
