Turns Ratio in Transformer Ratio Method Solution

STEP 0: Pre-Calculation Summary

Formula Used

Turns Ratio = Secondary Winding Turn Numbers/Primary Winding Turn Numbers
η = N_s/N_p
This formula uses 3 Variables

Variables Used

Turns Ratio - Turns Ratio is the ratio of the number of turns in the secondary coil to the number of turns in the primary coil.
Secondary Winding Turn Numbers - Secondary Winding Turn Numbers is the number of turns in the secondary winding of the transformer under testing.
Primary Winding Turn Numbers - Primary Winding Turn Numbers specifies the number of turns of the coil under testing in the primary side of the transformer.

STEP 1: Convert Input(s) to Base Unit

Secondary Winding Turn Numbers: 40 --> No Conversion Required
Primary Winding Turn Numbers: 101 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

η = N_s/N_p --> 40/101

Evaluating ... ...

η = 0.396039603960396
