What is AC and DC Current?

Or cycles

Or 50hz in Australia and other countries

My thing is incandescent bulbs blow out frequently, yet no one correlates the AC change in voltage to shortening the life span of an incandescent bulb when we know that frequently "on-off" requires more energy.

D.C. - its comix

Or 50 times a second

If AC is switching back and forth, then why only one of the cables from the socket is shocking me when i touch and other one not?

Now, the difference between the 2 on a practical level, is that if there is a small break in the filament, the DC bulb will just stay on because an arc will form at the break, but an AC bulb will go out immediately. The DC arc is very bad news in an MRI room because it emits broadband RF which screws up the images.

120 times a second. The direction changes as they reach the positive extreme and again at the negative extreme. That's the difference between an electrical engineer and a tyro who wants to create source.

60 times? I told its 200 times are you sure 😮

Mathematically, DC is AC at zero hertz

I can't picture it in my mind. I understand DC, but AC is cinfusing.

Isn’t it 50hz?

Not true, not everywhere!

So, in house hold electrical you have AC. If touch the black wire you will get a shock, if you only touch the white wire you won’t. If electrons alternate, why no shock when touching white wire?

Am i the only one expecting seeing the bulb turn on

We learned this in grade 6.

die beiden stromarten sind begrundet im generieren des stroms. batterien erzeugen immer dc, Generatoren wo magnete den strom durch Bewegung induzieren, zwangsläufig ac

It must be flashing fast, I can't see it.........

It switches twice per period. So it switches 120 times per second @60Hz, or 100 times per second @50Hz.

That is true

So ?

Nice

It changes direction 120 times per sec

Mate it is not direct current, it's de-alternative current. Thank you.

Duh

DC us a circular saw, AC is a reciprocating saw.

Why repeat it twice

I thought most people think AC is better then DC.
But I found that these a lot of back and forth.

50 hz in Germany and elsewhere. America uses 60 hz

You're absolutely right however with today's technology we can step up DC voltage

Electrons don't really 'flow'

so according to your theory the negative cable will actually be positive 50% of the time.

Bulbs blown mate.

why i only see a spiderman logo in bulb white colour ??

AC is more like a locomotive where the Piston goes forward and then backwards but the train still keeps moving forward

PERHAPS I USA, 60Hz 115 VOLT
BUT IN EUROPE 50Hz 230 VOLT

50Hz in EU !!!!!!!

50hz for me 220v

AC Current? Alternating current current?

I was about to rock, but no salute was made.

Interesting!👍

50/60hz depending

Is ac reversing the polarity of the electrons?

And the lamp does what?

wrong, electrons dont move.

Does anyone know what a Hz donut is? Hz donut ??? 😂

The electrons aren't moving down the wire, they are passing charge

Definitely not DC bulb, it's got Spider-man

In India 🇮🇳 frequency is 50 hz..

no lightbulb was hurt in producing this video.
