We know that charge of the electron is 1.6e-19 C and the work function of the electron is 1.6e-19 J can anyone descripe the relation between charge and energy and why the value remains same?

Work =3D energy =3D Fd =3D Force times distance
F =3DqE =3D charge times electric field - Force
E =3D electric field =3D volts per distance =3D volts per meter =3D V/d
multiply force eqation by distance to get energy
Fd =3D qEd
substitute electric field equation
energy =3D Fd =3D qEd =3D q(V/d)d =3D qV
energy =3D qV
units of electron volts =3D energy
1 electron volt =3D 1.6e-19 J=A0- Vote on answer
