Abstract

The abstract definition of electric tension as “the ability of an energy source to do work” or quantitatively as “energy per unit charge” is preceded by a qualitative description in terms of the existence of surface charges. These surface charges and the associated electric fields can be demonstrated experimentally and allow us a causal explanation of the processes and laws to be understood and learned.
