This is a fantastic video to introduce fundamental terminology & definitions that are often just glossed over and then which give rise to big conceptual problems later...very well done!
Amazing demonstration! Just a curiosity: Do both charges travel simultaneously towards each other due to attractive forces? And is it just a convention that the direction of current will be decided only by the direction of negative charges' movement? Thank you.
If positive and negative charges are free, then yes, they both move simultaneously towards each other. And in reality, the movement of charges depens on specific material. In most materials only electrons are moving freely. And yes, it is a convention that positive current is definied as movement of positive charges (not negative as you said). But it does not influence the physics.
@@mathathiknai Some atoms are positively charged - they are positive ions. Basically they have a hole of one or more electrons in the outermost electron shell. And they are in a some kind of metal alloy, which means they are firmly held in a crystal structure, crystal lattice. And negatively charged electrons are free and can move up or down the wire. So what actually happenes is - electrons move from one positively charged ion to the next one, filling the electron gap in the atom temporarily. Basically electrons move from - to +, which is analogous to the "electron hole" moving from + to -. (Something like that, if I remember correctly from my secondary school physics.)
Why did you place a negative sign in front of 0.5 A at time stamp 5.59 min. Can current have negative sign, or you are just doing for explaining since electrons moved through this demo circuit ?

The only thing I don't understand is: In reality, both positive and negative charges move toward each other. Isn't that supposed to nullify the current?

Thank you! :)
My goodness, finally I understood why I=dq/dt 😅
Thank you, Very well explained!
Thank you very much!
Very well explained!
Thank you!
Very nice,well explained thanks very much
Thank you
the most helpful video I have ever seen 🥰
Thank you very much! :)
thanks for good explains
Thank you !!

Yes, depends on the magnitude of the charge. (I guess)
Waiting for more videos of you sir
Thank you very much!
Good video. Thanks.

Yes, your understanding is correct! But the voltage source supplies the separated charges so that the charge difference is maintained.
good one
thank you!!
really cool video :3

pole cannot stay single pole
What do you mean?
@@fufaev-alexander like magnet. it must be dipole. not monopole
@@cedartse6705 that is a magnetic attribute you are talking about electrical poles can be monopoles
