Question

The resistivity or specific resistance is measured
A) O ohm-m
B)O ohm/m
C)ohm/meter cube
D) ohm/meter square​

Answer 1

Answer:

a) Ohm metre

Explanation:

R = ¢ L/A

here R is resistance in the circuit.

¢ is specific resistance. sorry i couldn't find proper symbol.

L is length of wire. A is area of cross section.

¢ = (R × A)/L = (Ohm × m^2)/ m = Ohm metre
