Volts to eV calculation with elementary charge

The value of energy E measured in electron-volts (eV) is apparently equal to the value of voltage V in volts (V), multiplied by the electric charge Q in elementary charge or the proton or the electron charge (e).

Learn to convert volts to electron-volts

You can simply convert the electrical voltage measured in volts (V) to energy measured in electron-volts (eV).

You can simply calculate the value of electron-volts from volts and elementary charge or coulombs, but it is to be noted that you can convert volts to electron-volts since volt and the electron-volt units with different quantities.

Volts to eV calculation with elementary charge

The value of energy E measured in electron-volts (eV) is apparently equal to the value of voltage V in volts (V), multiplied by the electric chargeQ in elementary charge or proton the electron charge (e).

The value of elementary charge is the electric charge of 1 electron with the e symbol.

So the value can be called as,

or

So the value can be called as,

electronvolt = volt × coulomb / 1.602176565×10-19

or the value can be called as,

eV = V × C / 1.602176565×10-19

For Example,

Find the value of energy in electron-volts that is consumed in an electrical circuit with the value of voltage supply of 10 volts with the charge flow of 3 coulombs?
