alleryIn the relation R equals rho l over A, the constant rho is the:
AReflectance
BResistivity
CResistance
DReluctance
Answer & Solution
Correct answer: B. Resistivity
1. This constant relates resistance to the shape of the conductor.
2. It is called resistivity.
3. So the correct answer is resistivity.
