AC and DC are different types of electric current. There are some significant differences and those differences are allowing for some interesting application especially with the changing face of energy awareness today. AC or alternating current is literally a current that alternates in the direction that it flows. DC is direct current and as is implied by the name the current flows only in one direction.

Alternating current replaced DC in the 1880s as the current used in power lines because of difficulty in transmitting DC over long distances. This problem has since been remedied and direct current is now transmitted over long distances, though AC remains the current type that is supplied to houses and businesses. AC allows for transfer of energy from the consumption point back into the grid as well as from the grid to the consumption point. This has proven beneficial in the case of houses and businesses that now produce more energy than they consume. This is being made possible thr ...more

The difference between AC and DC is that AC is an alternating current (the amount of electrons) that flows in both directions and DC is direct current that flows in only one direction; the product that is flowing being electrons. AC power is what fuels our homes. The wires outside of our house are connected at two ends to AC generators. DC is found in batteries and solar cells. Both AC and DC employ magnets to repel electrons. Electrons are negatively charged particles that are one of 3 components that make up an atom. Negative charges will repel negative charges and positive charges will repel positive charges, so one only needs to introduce a negatively charged item next to electrons to force them to move in the opposite direction. Likewise, you can attract electrons by introducing something that is positively charged into their environment drawing the electrons to it. This property of electrons is what allows for AC power to work; that is, they switch directions constantly. The pict ...more

When electricity flows in one direction, it is referred to as direct current (DC). Alternating current (AC) is when the electrons flow in both directions one and then the other.

high-voltage alternating current (AC), which could carry electricity hundreds of miles with little loss of power,DC can not be sent not beyond 1 mile or so as it looses so much as transition loss
