27. Two equivalent sets of units for electric-field magnitude are volts per meter (V/m) and newtons per coulomb (N/C). One volt is one joule per coulomb (1V-1 J/C). A useful unit of energy is the electron volt (eV), which is the energy corresponding to a particle with a charge equal to that of an electron moving through a potential difference of one volt. The conversion factor is 1 eV=1.602power-19J
