This chapter discusses the origins of voltage differences and presents several less expensive and practical techniques for determining the magnitudes of potential differences. High-voltage, low-current-based power supplies are described in Chapter 11.
Voltage is commonly accepted as a measure of the potential energy that makes electrons or a charged entity move during an electrical flow. It is defined as the energy per unit charge or energy = E/Q. A volt is a joule/coulomb. An electric field is created when electrons ...
