Answer:
Step 1:
Measure and record the resistance of the material by using an ohm-meter.
Step 2:
Measure and record the length of the material.
Step 3:
Measure and record the area of the material.
Step 4:
Calculate the conductivity of the material by using the formula given below
[tex]$ \sigma = \frac{l}{R \cdot A} $[/tex]
Explanation:
Electrical Conductivity:
Electrical conductivity is a measure of how well a material can carry current.
For example:
Copper material has high conductivity whereas plastic has poor conductivity.
The opposite property of conductivity is called resistivity.
Electrical Conductivity Test:
The electrical conductivity of a material can be found by
[tex]$ \sigma = \frac{l}{R \cdot A} $[/tex]
Where R is the resistance of the material, A is the area of material and l is the length of material to be tested.
Step 1:
Measure and record the resistance of the material by using an ohm-meter.
An ohm-meter measure the resistance according to the Ohm's law
[tex]$ R = \frac{V}{I} $[/tex]
Step 2:
Measure and record the length of the material.
Step 3:
Measure and record the area of the material.
Step 4:
Calculate the conductivity of the material by using the formula given below
[tex]$ \sigma = \frac{l}{R \cdot A} $[/tex]
Therefore, this is how we can find the conductivity of the material.
