Class A fire extinguishers are used on Class A fires, that is, "ordinary combustibles" such as wood, paper, cloth, rubber and small amounts of plastics.
Because it may contain conductive water, a Class A should never be used on an any other type of fire -- there could be a dangerous reaction.
Class A fires are fires that leaves behind ash, including wood, paper, foliage, etc. A Class A extinguisher is optimized for this type of fire, but doesn't work as well (or sometimes at all) on class C (chemical and grease, or "boiling" fires) or Class C (electrical) fires.
Class D fires (potassium, aluminum, etc.) are rare outside the laboratory and not typically considered in selection of an extinguisher for the average user.
Class A fires are wood, paper, fabric, and garbage or similar fires. Class C fires are any fire where energized electronics are involved.
Water mist fire extinguishers are only rated class AC. Dry chemical extinguishers are available as class ABC, as are larger halon and other clean agent extinguishers.
