Enter the electron charge (C) and the accelerating voltage (volts) into the calculator to determine the X-Ray Energy.

## X-Ray Energy Formula

The following equation is used to calculate the X-Ray Energy.

**Ex = ec * V**

Variables:

- Where Ex is the X-Ray Energy (J)
- ec is the electron charge (1.60217662 * 10^-19 C)
- V is the accelerating voltage (volts)

## How to Calculate X-Ray Energy?

The following two example problems outline the steps and information needed in order to calculate the X-Ray Energy.

**Example Problem #1:**

- First, determine the electron charge (C). In this example, the electron charge (C) is measured to be 13.
- Next, determine the accelerating voltage (volts). For this problem, the accelerating voltage (volts) is calculated to be 5.
- Finally, calculate the X-Ray Energy using the formula above:

Ex = ec * V

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

Ex = 13 * 5 = 65 (J)

**Example Problem #2: **

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

electron charge (C) = 74

accelerating voltage (volts) = 3

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

Ex = 74 * 3 = 222 (J)
