Electron volts
Posted in Physics, Charge and fieldElectron volts have been covered in AS Physics, they are a measurement of energy used in physics and you'll be expected to use them and convert between electron volts and joules.
Definition
1 electron volt (eV) is equal to the amount of energy a particle with the charge of an electron () gains when moving through a potential difference of 1 volt.
Conversion
To convert from joules to electron volts you simply divide by to convert from electron volts to joules just multiply.
