Enter the total impedance (ohms) and the transformer turns into the Calculator. The calculator will evaluate the Impedance To Turns Ratio. 

Impedance To Turns Ratio Formula

ITR = I / T


  • ITR is the Impedance To Turns Ratio (ohms/turn)
  • I is the total impedance (ohms)
  • T is the transformer turns

To calculate the Impedance To Turns Ratio, divide the total impedance in ohms by the number of turns.

How to Calculate Impedance To Turns Ratio?

The following steps outline how to calculate the Impedance To Turns Ratio.

  1. First, determine the total impedance (ohms). 
  2. Next, determine the transformer turns. 
  3. Next, gather the formula from above = ITR = I / T.
  4. Finally, calculate the Impedance To Turns Ratio.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total impedance (ohms) = 300

transformer turns = 4
