The Difference Between AC Batteries & DC Batteries Sciencing

WebDirect current is produced by batteries, fuel cells, rectifiers, and generators with commutators. Direct current was supplanted by alternating current (AC) for common commercial power in the late 1880s because it was then uneconomical to transform it to the high voltages needed for long-distance transmission. WebIt is cheaper but its maintenance is quite dangerous and costlier then AC. Hazard. The AC is less dangerous than DC because it reaches to 0V at some regular intervals. (not to be played with at high voltage) The DC is very dangerous and life-threatening then AC because it maintains a constant current flow. how to keep onions from moldingWeb17 sep. 2013 · According to Karl K.
