Enter the x-ray energy (J) and the electron charge (C ) into the Calculator. The calculator will evaluate the Accelerating Voltage. 

Accelerating Voltage Formula

AV = XRE / ec


  • AV is the Accelerating Voltage (volts)
  • XRE is the x-ray energy (J)
  • ec is the electron charge (C )

To calculate Accelerating Voltage, divide the x-ray energy by the electron charge.

How to Calculate Accelerating Voltage?

The following steps outline how to calculate the Accelerating Voltage.

  1. First, determine the x-ray energy (J). 
  2. Next, determine the electron charge (C ). 
  3. Next, gather the formula from above = AV = XRE / ec.
  4. Finally, calculate the Accelerating Voltage.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

x-ray energy (J) = 900

electron charge (C ) = 100
