## 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:**

- First, determine the total impedance (ohms). In this example, the total impedance (ohms) is measured to be 13.
- Next, determine the current (amps). For this problem, the current (amps) is calculated to be 12.
- 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)
