А куда вы вставили пропущенное слово particle?

Оно здесь лишнее - никуда не подходит.

1 Ohm - The unit of measurement applied to resistance. 2 Ampere - The SI unit of measurement applied to the flow of charge through a conductor. 3 Coulomb’s law - An equation defining the force of attraction or repulsion between two charges. 4 Volt - The unit of measurement applied to the difference in potential between two points. If one joule of energy is required to move one coulomb of charge between two points, the difference in potential is said to be one volt.
