Sample | A | B | C |
Resistivity |
Answer:
A
material having low resistivity is a good conductor.
Since, resistivity of sample A is the least among all other materials, so
sample A is a good conductor. (1)
A material having high value of resistivity is an
insulator. Therefore, sample C is having high value of resistivity
among all materials. So, sample C is an insulator. (1)
