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.

Really nice clear video! A few small things: the bulb would flash 2x the frequency of the current (so 100x for 50Hz, or 120x for 60Hz.) And an incandescent lightbulb won't flash because they're electricity -> heat -> light, and the cycle is too fast for the filament to cool down in between cycles. Whereas a LED light will flicker because it's electricity -> light. This explanation would be perfect for something like an LED bulb.

@AddOhms

You are hardly the first to point out the 2X rate mistake after all these years. (Salt in the wound.) As for flicker, sorry, minor mistake on my part is that incandescents don’t flash. A better description is pulsate. Plenty of high-speed footage confirms that. Also, LEDs “pulsate” as well. Though, of course, their curves are *much* sharper when compared to a tungsten filament.

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.

Also check the article from askanydifference which goes into minute details of Alternating and Direct current differences.

Do all of the electrons move or just bump into each other?

So, if AC in light bulbs have a frequency of 50Hz and that the bulb is flashing 50 times a second. so what if we connect AC to a fan? does it change direction?

If a DC fan was connected to an AC circuit, yes it would try to alternate back and forth very quickly; however, the motors used in AC circuits is actually a different kind of motor all together.

AFAIK, two reasons: 1- generators make AC current; and 2- AC current is easy to transform in higher or lower voltages. High voltages are great for transport in power lines but dangerous at home. Edison favoured not just DC current, but local generation of power (a generator in every home or housing block), but Tesla was convinced that big power stations generating for whole cities, then distribution grids was the way to go.

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.

why we need this two type of current ?

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.
