An electron is accelerated by a potential difference of, say, 100V. How much greater would its final speed be if it were accelerated with four times as much voltage?
An electron is a subatomic particle with a negative charge that orbits the nucleus of an atom.
Potential difference, also known as voltage, is the difference in electric potential energy between two points in an electric field.
When an electron is placed in an electric field with a potential difference, it experiences a force that accelerates it towards the positive end of the field.
Potential difference is measured in volts (V).
The higher the potential difference, the greater the force on the electron and the faster it will accelerate. However, the speed of the electron will eventually reach a maximum as it approaches the speed of light.
