Thank you very much for posting this! You helped me better understand what volts and amps are!

Finally a good/clear and well delivered video..

this video is very good explains the basic concepts of electricity and electron flow in a circuit. for someone who wants to understand some electricity is very helpful. by: brayan torres

Good video ...like the way you deal with one idea at a time ....so many teachers jumble up ideas when lecturin ...like many music tutors!

A current is measuring the rate the electrons are moving. Currents are measured in amps (short for amperes). One amp stands for 624,0000000000000000, 16 zeros. Hope this helps.

Please post these useful videos on TeacherTube, so that schools who block KZread can also use them. Thanks!

It is very complicated to explain what happens to the electrons after they get to the + side of the battery . But a physicist can understand it .

@Greathoof Good day actually it is Canadian. The principle is universal. We also use 240v (really it is 236, but stated as 240) on our large appliances like clothes driers and electric arc welders, some air conditioners etc.

Hello, An early guess about the nature of electricity suggested that some sort of positive particles flowed from + to -. This is referred to as "conventional current" The discovery of the electron led to the realization that electricity is probably a flow of electrons from - to +. This has led to a confusing situation with text books using one or the other or both explanations. I prefer the electron model.

nice video but got a question what does actually cause the flow of electrons out of the battery , when metallic conductor will adjust to it?

very well explained

moving ions (positively charged atoms) also create electric current therefore their movement is also "electricity"

Can anyone tell me how fast electron moves in a circuit. In one book i found, it moves very slow yes almost at dead slow speed (which i agree). Other say it move with speed of light which i disagreeeeee :). Also do you think higher voltage in circuit moves the electrons faster or slower?

Yes, very interesting. Would love to see more like this.

250 years ago Benjamin Franklin proposed that electricity was a flow of charged particles moving from "plus" to "minus". This was a guess, but it became the accepted model for electricity. He probably also introduced the concept of "ground". We now know that the charged particle is the electron and it actually moves from "minus" to "plus". Unfortunately Franklin's 200 year old guess still influences the vocabulary of electricity and electronics causing much confusion.

@cricka09 It can kill you by contact. In that case I'd call it high voltage. The point I think is that it is high enough to be easily fatal.

thank you

@DrJohnCockwalrus so why do we treat photons as particles even though we accept the idea of them having no mass and being pure energy? Why dont we treat them as waves, and ONLY waves?

electromagnetism might just be one of the most interesting parts of physics

It does mean the length. Shorter wires tend to get hotter faster because there's less space for the heat to dissipate and disperse over.

Thanks , your video helped me alot :)

Can someone please tell me what happens to the electrons after they get to the + side of the battery. Electricity is the flow of electrons what leaves the - terminal flows to the + terminal so do they vanish?

Pretty cool!

Really good! I love it alot.

yeah. im pretty confused abt tht. people usually say electrical current flows frm + to -, while at the same time acknowledging tht electron flows in the opposite direction. how is tht?

Can any body out there can teach me or guide me, I'd like to put together lots of very bright led's, and run it with batteries, at least i want to plug 100 and make them flash from one side, to the other, like running. . . . .thanks i have already few led's and a soldering gun... THANKS AGAIN. cheers!!

yea good video

great video but 120 volts is not high voltage

Cool

circuit cant be closed without any resistance

I have never seen an electron, does that mean its magic? Invisible magic?

Great, thanks!

cool post

ah, but the expanded form is more dramatic
