The resistivity of a material is 2x10-3Ωm. What is the conductivity\n

Conductivity,

Explanation:

Given that,

The resistivity of a material,

We need to find the conductivity of the material.

We know that the reciprocal of resistivity is called conductivity.

So, the conductivity of the material is .

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
