is resistance of a conductor is same as its resistivity ? write any 2 factors on which a resistane depends upon.
Answers
Answer:
Resistance is directly proportional to the length and inversely proportional to area. Another factor that affects resistance is temperature because the resistivity if a function of temperature. It increases on increasing the temperature of the substance.
Explanation:
resistance depends on following factors:
1) Length: It is directly proportional to resistance of the conductor.
2) Area: It is inversely proportional to resistance to the cross sectional area of the conductor.
3) Temperature: It is directly proportional to resistance.
4) Resistivity: It is directly proportional to resistance of the conductor.
Formula showing relation of resistance with these factors.
R = (p*l)/A
where, R = resistance; p = Resistivity; l = length; A = area
Answer:
No because resistance and resistivity are different
Explanation:
resistance depends on length, area and nature of the material also where as resistivity depends on only nature of the material
