Introduction to Electricity

http://hilaroad.com/video/ This video explains electricity as the flow of atomic particles called electrons. Animations demonstrate electron flow. Batteries are described as chemical devices designed to create electron flow. Terms covered in video include Volts, current and Amperes.

hi...

i learnt that conventional current flow from + end to - end....

and...can you explain why is it different from the one you mentioned in your video?

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.

thanks for this video, I am a first year apprentice only been in the trade for 6 months. I want to know it ALL and be the best ever!

@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.

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

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..

LoL. I was wondering "120 volts... that looks kinda weird...." then realized this is made for Americans :D (In EU, we use 240V)

Thanks , your video helped me alot :)

[cricka09]

great video but 120 volts is not high voltage

[latinoheatwhoa]

i am an apprentice in europe as an electrician and this video is fantastic

Great Video, thank you for sharing it.

Nice Video! I like when, you know, something interesting and useful actually gets posted on YouTube.
