Charge & electric fields
•The potential
energy of a charged particle in an electric field is proportional to its charge - the electrical potential difference between two points in the field of which a potential energy of 1 C charge changes by 1 Joule, is defined as 1 volt
(V).
•
•1 Amp represents the transfer of 1 coulomb of charge per second
