Enter the maximum kinetic energy (J) and the electron charge ( C) into the Calculator. The calculator will evaluate the Stopping Voltage.

## Stopping Voltage Formula

SV = KE/e

Variables:

- SV is the Stopping Voltage (volts)
- KE is the maximum kinetic energy (J)
- e is the electron charge ( C)

To calculate Stopping Voltage, divide the maximum kinetic energy by the electron charge.

## How to Calculate Stopping Voltage?

The following steps outline how to calculate the Stopping Voltage.

- First, determine the maximum kinetic energy (J).
- Next, determine the electron charge ( C).
- Next, gather the formula from above = SV = KE/e.
- Finally, calculate the Stopping Voltage.
- 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.

maximum kinetic energy (J) = 45

electron charge ( C) = 20
