Current and Amps: What are they?
ฝัง
- เผยแพร่เมื่อ 11 ก.ย. 2014
- ERROR!!!!: At 1:14 in the video, the 28 should be an 18.
This explains what electric current and amps are using animations and practical examples. Along the way it also shows what charge and coulombs are, and the amps is coulombs per second. Also cleared up is conventional current, and Benjamin Franklin's involvement, and that current also comes in the form of moving ions, corona, sparks and arcs.
Error: At 3:06 in the video, the formula V=I/R moves across the screen. It should be V=IR. Thanks to the viewer who pointed it out.

Another excelent learning tool. No doubt I will be pasting this link all over the internet fom many years to come.
Mongrel Shark Thanks man! I'm glad you like it.
Great video Steve. How long does it take to do animations like that? Hats off!
Grant Thompson - "The King of Random" Thanks Grant! I'm getting pretty experienced at doing the animations so not as long as you'd think. The Benjamin Franklin animations took only around 2 hours to draw, animate, and insert. Total time for this video was around 4 days: research & scripting, filming live stuff, recording voiceover, drawing 3D models and animating, editing (including text and other annotations), beginning and end stuff, audio fine tuning, and music.

My latest video: What are Current and Amps? Enjoy!
A gem of an explanation. Thanks for sharing. The Franklin info was enlightening and much appreciated.
chopsddy3 Thanks. Yeah, the Franklin info took some digging and was interesting for me too. Glad you found it so too.
If only I have seen this when i was younger. Nice work, and a brilliant video.
I always have trouble not getting voltage, current, amps, joules, coulombs, and measurements of energy mixed up. I started making a chart with definitions of each but, lost track of what I did with it. I frequently have to remind myself about the differences between them so, this was very useful to me. Great job!
The Pheuzitionist Thanks! You're just the person I mainly made this for then. I'm like you and like thinking of these things in terms of their more descriptive units: joules, coulombs, and seconds. I'm going to do a few of these videos centered around them.
Awesome! I look forward to seeing them!
Great video! Thank you Grant Thompson "The King Of Random" for sharing this.
Excellent work Steve! Very impressive content, animation, and editing. Well done!

SonicDadDotCom Thanks Ritchie!
Someone who has annotations off will not see that mistake(@ 1:14 min)! This video should have been removed and edited or re-done!
This is very well explained, thank you.
eucalyptux You're welcome, and thanks.
Excellent editing!
joshcryer Thanks!
Thank you very much this video was very good and helped reinforce some of my understanding I am very thankful for you taking your time to make these videos please continue to awesome :)!
great explanation I loved it
Thank You ! Great explanation ! :)
Great video!
James Biggar Thanks James!
My boy warned us about corona eight years ago, it was electric current and amps that did it. Great video tho mate!
Thanks! Yup, that's the culprit! And thanks for checking out my video.
So it mean that Amps is the speed of voltage flow in the wire or circuit, correct ?
Your videos should be shown in schools, are well done
Lechoslowianin Actually, from the teachers I hear from some of my videos are!
I diode symbol also resembles a check valve... so if a ball is put into a V shaped area, it will allow flow in one direction and not the other, so although it looks like a arrow, it actually resembles a check valve which is easy to understand.
J Decker Nice! I've never thought of it that way. Thanks!
Nice video! I have to admit the conventional current issue does annoy me, but what can you do. :)
GoRepairs Thanks! Yeah, sometimes I wish we had time machines. :)
RimstarOrg Something tells me if you went to the 1890s you would have tough time convincing them that science should change conclusions to match the evidence. Going back to see Ben you might miss the trip back as the old boy pumped you for information.
Very well explained! You have great videos! Can you try to do a tesla field gerator (i think you already did it) but then put a fluorescent lamp near it, the lamp will light up, why?
Joel Santos If you mean tesla coil, I haven't made one yet. It's still on my list though.
RimstarOrg oh, yes a tesla coil...in that case I can´t wait for that! Thanks for replying!
OMG THANK YOU SO MUCH
kevin leach My pleasure! Glad it helps!
Nice man
Thank you
What i do not understand (and it might sound like stupid to you) is lets say for example we have 1 unit of electricity and this unit comes through the positive cable? into our house,and our laptop uses this unit,but then this unit leaves our house and goes back to the production (i guess). What changed in the one unit of electricity from the moment it came inside our house,to the moment it left the house ? (if i am mistaken please let me know)
Lord Hactivsm The change is that it lost some energy when going through you laptop, mostly ultimately to heat, but also some to electromagnetic energy emitted by various components and the screen. It shows up on a volt meter as a voltage drop across the ingoing and return wire to the laptop. Voltage is volts but is also joules/coulomb which is energy/unit charge. I'll be talking about voltage in another video. There is also a decrease in current with the laptop versus without, since the laptop adds up as a resistance.
RimstarOrg Excellent Video, RimstarOrg. I would like to add on the answer to the question above. It's actually a very good question. An alternative way to answer the question Hactivsm posted is to use the analogy of the stream of water and a paddle wheel. See, to move a paddle wheel you don't actually consume the water - the water is the carrier of energy - and the energy is given by the slope of the stream of water. A flat or near to horizontal river will not turn the wheel efficiently but a steep slope will move it much better. In the electric circuit the slope is what we call the Electrical Pontential Difference - which is measured by your 110V on the outlet. There are several post on youtube to describe that and other analogies and I suggest you dig a bit if this rings a bell to you.
it looks great
Hermann Kateri Thanks.
Rimstarorg isn't 1C= 6.24*10^18 electrons ? I think you made a mistake at 1:10.
John C Sunil Ouch! Thanks for pointing it out. Must have been a typo. I added an annotation to that part of the video. That's an embarrassing one to have in there.
is it possible to measure the current with a digital multimeter without breaking the circuit like that?
Yes, you can use a clamp meter. The clamp part goes around the wire. en.wikipedia.org/wiki/Current_clamp en-us.fluke.com/products/clamp-meters/
Thank you so much!
Gehab So AWESOME!
Dafuq? Wrong video!
IS there a repulsion between electrons while moving in a wire?
There's probably some. There are an awful lot of electrons and their movement is pretty chaotic. They're usually animated as moving in a straight line but that's just a simplification. Overall though, their movement is in one direction.
thank you so much for your awesome video
How works the Keshe reactor ? keshefoundation.org
1 Coulombs =6.24×10^18 electron charge
Yeah. Unfortunately you can't edit videos once they're up but TH-cam used to have a feature called annotations which allowed you to add text on top of the video and so I once had an annotation pointing out my error. Annotations don't exist anymore. So I just now added a correction to the very top of the video description. Thanks for the reminder!
This reminds me of lipo batteries. It'd be neat to see the science behind how they work. Future vid? These guys explain the basics, but it would be neat to have an in depth explanation th-cam.com/video/K6hGvXxFTFA/w-d-xo.html
I'm even more confused. So everything ive been told is backwards?
That depends on what you're referring to. If you're talking about the direction of current in a wire, I talk about the two different conventions starting around 1:58.
Are you sure V=I/R? (see the formula shown at 3:07)
Oh wow. Good catch. It should be V=IR of course. Sadly there is no longer the ability to add new annotations to videos otherwise I'd put one there. I'll add something to the video description. Thanks!
Sir थ्री फैस बिजली के कनैक्शन में ampere से unit कैसे बनाए
smart enough
1:21 That's 62 Octillion 410 Septillion electrons in 1 amp 😂
you said coulombs are amps? bob is not joe! and their must be a difference between the two. i think? coulombs are electrons 628/18 per second or 1 coulomb. amps are in hours. consequently, their is possibly a difference one is in seconds the other in hours. is this the difference between the two assuming their is one. because i dont think amps is directly equal to coulombs. it also appears that amps is an abbreviation for coulombs?
Coulombs per seconds is amps.
@@RimstarOrg coulombs is 628/18 electrons, its a charge. when it travels at 1 second it becomes amps. the difference is amps has the time and is an equation, coulombs is just a charge. i think this is correct.
You should have explained that there are two electric current theories. You first talk about the ELECTRON THEORY which is correct and then move to the CONVENTIONAL CURRENT THEORY which is wrong but still used in electronics. You could have also explained the difference between the actual electron flow in a conductor and the electric effect of current in a conductor, because they are very different and electric effect is the actual working force of electricity.

All he has to do is make a comment or subscribe to my channels. If he doesn't call me a idoit he is in.
TefnutUaRaet
He has to believe in himself first. you can help there.
I guess I was completely wrong or at least slightly.
@1:15 you say a coulumb is 6.421x10^28, in the other video you say it's 6.421x10^18 th-cam.com/video/E8bdspoPtXk/w-d-xo.htmlm5s
th wikipedia says its 6.421x10^18 too en.wikipedia.org/wiki/Coulomb
Jerónimo Barraco Mármol It was a typo in my script and I didn't catch it until someone commented after uploading. If you turn annotations on you'll see I have an annotation pointing out the error. Thanks for bringing it up anyway.
RimstarOrg sorry for bringing that up again. i hate annotations so i dont see them. i actually asked because i was interested. i hope you didnt mind.
Jerónimo Barraco Mármol
I didn't mind at all. I mind when people don't point out errors. So your bringing it up was much appreciated.
RimstarOrg if you want to see it from the bright side, i was paying attention to your video :)
a already knew of electricity and electronics from my high-school (is a technical school (i'm actually a technician in electricity and industrial electronics from high school)) but i wanted to refresh and deepen the knowledge and your explanation is the best i've found around. mostly to understand the difference between volts and amperes (the j/s remark was great). thanks a lot!
well nowadays corona is really in the air..
😅😅😅😅😅😅well information good show you 😅😅
😅😮😅😮😅😮😅😅😅😅😅😅😅😅😅😅well information good show 😅😅
Conscientiousness please! @ 1:14 min.
I don't understand. If you're referring to the error I made, there's an annotation there (which not all devices show :() that points out it should be 6.241x10^18.
