Uncover the speed of an electron with our intuitive Electron Speed Calculator. Easily determine electron velocity when accelerated by an electric potential difference (voltage). Essential for understanding particle physics and electron beam devices, this tool simplifies complex calculations, providing instant and accurate results for students and engineers.
Formula:
The electron speed (v) is calculated using the formula derived from kinetic energy and electric potential:
KE = ½mv2 = qV
Where:
v = √(2qV/m)
- v is the electron speed in meters per second (m/s)
- q is the elementary charge (1.602 × 10-19 C)
- V is the accelerating voltage in Volts (V)
- m is the electron mass (9.109 × 10-31 kg)
