## Peak Current Formula

The following formula is used to calculate the Peak Current.

Ip = Irms * 1.41421356237

- Where Ip is the Peak Current (amps)
- Irms is the root mean square (rms) current (amps)

To calculate the peak current, multiply the root mean square current by** **1.41421356237.

## How to Calculate Peak Current?

The following two example problems outline how to calculate the Peak Current.

**Example Problem #1:**

- First, determine the root mean square (rms) current (amps). In this example, the root mean square (rms) current (amps) is measured to be 50.
- Finally, calculate the Peak Current using the formula above:

Ip = Irms * SQRT(2)

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

Ip = 50 * SQRT(2) = 70.71 (amps)

**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:

root mean square (rms) current (amps) = 30

Entering these values into the formula above gives :

Ip = 30 * SQRT(2) = 42.426 (amps)
