A C is alternating current. D C is direct current. In A C the current travels in two directions where D C current flows only in one direction. A C power is what most people have in their homes. The current travels from A C generators to the outside of our home on two wires. D C is found in batteries. So if you have a radio or c d player that has a button to change from A C to D C then your radio
. or c d player can be plugged in for A C current or use a battery to get D C current to operate it. What is alike of the two currents is that they both use magnets to repel electrons.Thomas Edison founded the process of D C current. He used it in lighting but could not carry it far enough to work from long distances. For D C power loses it power as it moves away from the source. Nikola Tesla founded A C current that we use in our homes. The A C current loses power in a lessor fashion. When the power reaches a power pole it is the ported through a transformer that lowers its current and we are able to use in our homes for our electrical appliances and the such.
