Basic Electricity - What is an amp?

Hi...it matters when I charge the laptop with a different charger that has 2 amps more.. (the original one has 20 w 4 amp, and these 20 w 6 amp)...the battery is defective and I keep it in the laptop just to not turn off the laptop suddenly when the power goes out...I tried with a charger with 3 amps but the laptop its work slowly...thanks..

This is the best thing ever

My IDEA is that current flow is when ever u manipulate it to go but electrón flow is unly to the ( - ) SIDE or what i call the one who needs more charge than the other. And ofcourse electron will go there through the one is at the biggining of any 🖇️ ,plus the first one Will offer less resistance than the resiver .that way is the way of efficiency ... own concept ok if is use full so take it i AM sharing.

proton are the positive charge partials that are part of the nucleus not the nucleus its self. I just learned this in school

I'm sure nobody pulled the number 6.24 x 10^18 out of a hat. You probably should have explained where the definition of ampere comes from.

A minute and 3 seconds into the video and my mind is blown

Good

this 11 years old content is really useful to me

Im 27 and i now understand electricity. Thank you!

I like the way you simplify this stuff. This is the way. Thumbs up

I'm lost thx for trying I just wanna know why I would want to increase amps over volts or vice versa

Thank you

Great Video to be honest .

I'm pretty sure at high enough charges the electric potential / gradient becomes so high, it can pull electrons right through the air. Lightning is proof of that. Air is resistance only. An as proven if the resistance is over come it can jump. I only say this because i believe the subject is miss understood because when it's "simplified" little facts that make all the difference in understanding the subject better, are lost.

So so good :)

So... does "electrical current" refer to "the flow of electrons"... or "the amount of electron flow"?
It's confusing. Some people say it's the first, others say its the second and this video first says it's nr.1... then later says it's nr.2.
Which is it?
Anyway, the positive to negative makes sense, cause for a split second when an atom loses electrons, it is positively charged... until one of the atoms before it in the circuit causes it to again be negatively charged- and then that atom is positively charged and so on.
So while elctrons are flowing in one direction, you can envision that "positive charge" flows in the opposite direction- hence "conventional current" (which is correct- just that it's "positive charge" that's flowing the other way, and not electrons)

Why don't they just fix the conventional current formulas to have electrons flow negative to positive? I'm sure there's a reason but it seems really simple to me to just figure out how to rewrite it with negative to positive flow

the best part was roxas joining the conga line

Tengo problemas con el asunto de la corriente convencional y la real. ¿Cual fue la conjetura que hicieron? ¿Cual fue su razonamiento? ¿Por que un polo se llama positivo y el otro negativo? Se supone que uno esta cargado negativamente al tener exeso de electrones, pero eso significa que en el flujo real le cambiaron el nombre al negativo o esto ya se sabia y se utilizaba esta nocion.
Si tomo una pila los electrones fluiran de la parte negra (indicada como negativa) a la dorada (indicada como positiva)
o fluiran de la parte dorada (que en realidad sera la negativa en el sentido real) a la negra.
¿Que experimentos se pueden hacer en casa para saber la direccion de la corriente?
¿En que orden ocurrieron los descubrimientos de positivo y negativo? y que experimentos se hicieron para demostrar estos errores?

I wish you were my physics teacher. You explained it very good sir.

Schwarzenegger in the end 🗿😭
By the way the clearest explanation I ever listen to,this is how our teachers are supposed to explain and I believe this is science not the memorization of formulas

Ooo my God. It is so simply explained! Thank you!!!!!!

Hello Thanks From France

Wait a minute...so if us doing it backwards is what produces light...is doing it proper what does it produce?

So the atoms don’t travel? The only thing that travels are the electrons? So the electrons push each other and leap frog over each atom? Is this right?

There's an ear in Ampere. Amp-ears not Amp-airs.

♥Thanks for simplifying the information

Thank you ☺️🌺

How is it possssible that the electrons move @speed of light?

Excellent, excellent video. I am an aspiring avionics intructor that's still working in the field since '05. This is an inspiring video. Its one thing to work in the industry, its whole other thing to teach it.

But nobody says why these electrons are moving? What is forcing them to move? Why they have to move from one point to another point?

perfect video

Simple, concise and illuminating! Thank you!

Hey! I know that. An amp. is the abbreviation of Ampere. It's a French dude the unit is named after.

Keep up the great work man

Finally I have understood it

Are you absolutely sure about this?

Excellent excellent excellent

why cant electrons move through the air on the open circuit?

I've taken several college courses now and not once has anyone ever mentioned conventional versus electron flow. But a lot of things are clicking in my head now.

Just one thing I don't understand about battery. Why we call the positive side "the positive"?

Finally it's clear to me!

Very good explanation, especially the part about conventional flow vs. actual flow.

So understandable and funny. "Very handy for when you dont want to die in a terrible fire." :D

Is conventional current same thing as initial current? I have 12V 1.2 Ah sealed lead acid battery and it says it's initial current is 0.36A and it's cycle use is 14.4 - 15V

Thanks! In my native language (Dutch) there wasn’t any good explaination to what amps truly are. They just explained it based on the Formula watts/volts.

Now i finally get it :)
