Question

If the dimensions( length and area of cross-section) of a conductor are changed then its:
A) resistance and resistivity both changes
B)resistance remain same but resistivity changes
C)resistance changes but resistivity remains the same
D) both remain unchanged​

Answer 1

Answer:

Resistance and sensitivity both change

Answer 2

Answer:

answer is A

Explanation:

because resisistivity=(resistance*area of cross section)/length of material

And resistance of conductor is inversely proportional to area of cross section of conductor and directly proportional to the length.
