Enter the total voltage (volts) and the number of coil windings into the calculator to determine the Coil Voltage. 

Coil Voltage Formula

The following formula is used to calculate the Coil Voltage. 

CV = TV / CW


  • Where CV is the Coil Voltage (Volts/winding)
  • TV is the total voltage (volts) 
  • CW is the number of coil windings 

To calculate the coil voltage, divide the total voltage by the number of coil windings.

How to Calculate Coil Voltage?

The following two example problems outline how to calculate the Coil Voltage.

Example Problem #1:

  1. First, determine the total voltage (volts). In this example, the total voltage (volts) is measured to be 50.
  2. Next, determine the number of coil windings. For this problem, the number of coil windings is calculated to be 3.
  3. Finally, calculate the Coil Voltage using the formula above: 

CV = TV / #CW

Inserting the values from above and solving the equation with the imputed values gives: 

CV = 50 / 3 = 16.667 (Volts/winding)

Example Problem #2: 

Using the same process as example problem 1, we first define the variables outlined by the formula. In this case, the values are:

total voltage (volts) = 400

number of coil windings = 100

Entering these values into the formula or calculator above gives us:: 

CV = 400 /100 = (Volts/winding)
