AC Motors use Induction. The coils around the stator (stationary part) create a magnetic field that induces a current on the rotor (spinning part.) The two fields react and cause movement. Since AC is "moving" back and forth, it creates a rotation. en.wikipedia.org/wiki/Induction_motor Neither AC nor DC are "better." AC is used for Mains because > 100 years ago, it was cheaper to step it up to high voltages and down to 100/200 volts for use in homes. That's it. And don't forget, "AC" does NOT just mean "Mains" voltage. All signals contain both an AC and DC component.

A little clarity on the lightbulb example used. An incandescent lightbulb has a certain amount of latency in the way it works, so when the voltage drops towards zero the filament takes time to cool and so still emits light for a while. This latency is long enough that before it can dim significantly the voltage has had time to increase on the other side of the sine wave and heats up the filament again. This smooths out any flickering that may occur. If you switch an LED at the same rate (50/60 hertz) you may notice some flickering. Note: the incandescent bulb is actually being lit 100/120 hz rather than 50/60 hz as it lights on both halves of the sine wave or twice a second. The LED only works with current in one direction so this wastes half of the power.

Magnets - a magnet has a magnetic field. As it is spinning inside a coil of wire, every time the magnetic field cuts through the wire, it pushes the electrons cresrig voltage. When the North part of the field cuts through, it pushes the electrons (which is the positive voltage) and when it spins around and the South part of the field cuts the wire, it pulls the electrons (which is the negative voltage). It spins in the US at 50 hz (50 times a second) so you get 100 peaks or "pushes and pulls" and max voltage 100 times a second. It happens so fast our electronics don't slow down and we don't notice.

I know you stopped at one cycle in your graph to see its corresponding animation current direction, that is too bad because it would have proved my point that the current changes 120 times in one second. Will, more like 119 times to be totally precise. The light flashes every time it crosses the line. Flash means change in direction.

Except probably not for incandescent bulbs. If you still have any, you’ve no doubt noticed that the filament (tungsten metal usually) still flowed for a moment after you cut the power. The cycle time is so fast that the filament stays at a relatively constant brightness while the power is on. But I believe this flashing phenomenon is why old and cheap LEDs make your waving hand in front of them appear to strobe. Also why LEDs strobe when you play back a slow motion video with LED light.

+MiKE Carry Yep, an unfortunate point of confusion, one we physics teachers struggle to get across. ELECTRONS flow from neg to pos, but, unfortunately, current (often shown as "I") is typically shown as flowing in the opposite direction. Not sure of the history of that; maybe way back when, someone just made a bad guess. So consider current flowing from the positive terminal as positive current, while current flowing from the negative terminal is, you guessed it, negative current. For my part I always showed the electron flow ("negative current") only, but you just gotta live with it.

That's my theory. Maybe I'm right...I don't know :P.

AC is easy for home, because plug is not polarized and you can plug it either way and you device works, further more in DC devices there has to be considerable measures taken when you plug the power in the wrong way normally this destroys DC operating devices. Also most of home devices operate motors, and motors work on AC current, your fridge fan, lights and electric ovens all operate on AC without need of much extra circuitry. It's only for a couple of decades we have many DC devices like computers, but still majority of your home appliances rely on AC for power. AC is better for long distance travel. Every time you need to convert from AC to DC there's hardware and power loss, and as I said all power hungry devices run on AC by default. There are also transformers which must be supplied with AC and alow easy change of voltage. Really AC is just better we only use DC when it is necessary for the operation, that mostly is in electronics.
