1 Way Vs 2 Way?
a: Alternating current ~
b: regular tide
What: "Direct current is a electric current that flows in one direction. That is to say that it travels around a circuit like the water in a river, never flowing backwards. On the other hand, alternating current is like a very regular tide. Flowing from nil up-to maximum in the positive, then flowing back to nil, and then flowing up-to maximum in the negative, then returning to nil again. This pattern is repeated forever."
