What is the formula for the resistance of running winding?

What is the formula for the resistance of running winding? Correct Answer resistance of running winding = 0.021 * no of turns in running winding * length of mean turns of running winding / area of running winding conductor

First the no of turns in running winding along with length of mean turns of running winding and area of running winding conductor is calculated. On substitution the resistance of running winding is calculated.
