Question

We use___________
to test the conductivity of a material.
​

Answer 1

Answer:

Calculate the electrical conductivity from the resistance, length and area of the current. The resistivity is given as p = RA/l where p is the resistivity, R is the resistance, A is the area and l is the length. The conductivity is s = 1/p where s is the conductivity.

Explanation:

Answer 2

Answer:

The following steps will allow you to measure and calculate the electrical conductivity of a metal. Use an ohmmeter to measure the resistance of a metal sample of known length and area. A basic ohmmeter would use two contacts, one at each end of the sample, to determine resistance.Calculate the electrical conductivity from the resistance, length and area of the current. The resistivity is given as p = RA/l where p is the resistivity, R is the resistance, A is the area and l is the length. The conductivity is s = 1/p where s is the conductivity.
