DEFINITION

Classification: 205/711

Simple alternating current:

(under subclass 710) Subject matter in which electric current passing through the electrolyte (usually between an electrode and a workpiece) can be represented by a smooth sine wave having equal amplitude above and below a straight line ordinate at zero current (e.g., pure alternating current, etc.).
