Is a Battery AC or DC? Explained in Simple Terms

The question of whether a battery is AC or DC is a common one, and the answer is simple: a battery is a DC, or direct current, source. Unlike alternating current (AC), which operates by constantly changing direction, a battery provides a steady supply of current in one direction. Direct current is the type of power that is produced by a battery
