Enter the drift velocity (m/s) and the external energy provided by the electric field (J) into the Electron Mobility Calculator. The calculator will evaluate the Electron Mobility.

## Electron Mobility Formula

The following two example problems outline the steps and information needed to calculate the Electron Mobility.

u = Vd /E

Variables:

• u is the Electron Mobility (m^2/(V-s))
• Vd is the drift velocity (m/s)
• E is the external energy provided by the electric field (J)

## How to Calculate Electron Mobility?

The following steps outline how to calculate the Electron Mobility.

1. First, determine the drift velocity (m/s).
2. Next, determine the external energy provided by the electric field (J).
3. Next, gather the formula from above = u = Vd /E.
4. Finally, calculate the Electron Mobility.
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.

drift velocity (m/s) = 300

external energy provided by the electric field (J) = 235

u = Vd /E = ?
