Enter the total impedance (ohms) and the current (amps) into the calculator to determine the Voltage From Impedance. 

Voltage From Impedance Formula

The following formula is used to calculate the Voltage From Impedance. 

E = Z * I 
  • Where E is the Voltage From Impedance (volts)
  • Z is the total impedance (ohms) 
  • I is the current (amps) 

To calculate the voltage from impedance, simply multiply the impedance by the current.

How to Calculate Voltage From Impedance?

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

Example Problem #1:

  1. First, determine the total impedance (ohms). In this example, the total impedance (ohms) is measured to be 13.
  2. Next, determine the current (amps). For this problem, the current (amps) is calculated to be 12.
  3. Finally, calculate the Voltage From Impedance using the formula above: 

E = Z * I 

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

E = 13 * 12  = 156 (volts)

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 impedance (ohms) = 11

current (amps) = 9

Entering these values into the formula above gives : 

E =11 * 9 = 99(volts)
