An electron accelerated by V volts has a kinetic energy of V electron volts.
That's how the electron volt (eV) is defined.
An electron accelerated by 1.0 V gets an energy of 1.0 eV.
An electron accelerated by 10 V gets an energy of 10 eV.
And an electron accelerated by 10^4 V gets an energy of ...?
