I am confused. Current is defined to be the rate at which charge flows. So let's say that 1 positive charge and 1 positive flow through an area per second so the current will be 2 charge per second right?

@WilliamJohn Yes

I am also confused about direction of current. It is defined as moving positive charge from positive terminal to negative terminal. What if I say both positive and Negative move in opposite direction through an area at same rate? What is use of defining a direction?

The direction of current has confused generations of physics students :-)

It was defined before people knew that electrons existed, and by chance the direction of current was defined as the opposite to the direction that the electrons move. This is unfortunate, but the convention is too deeply established for it to be changed now.

Ah I get it I understand why I am confused.

I was thinking about two direction at same time.

Thanks for help again ·u·

@JohnRennie Are you free ?

@KavinIshwaran Hi, yes I'm free :-)

Shall we continue to discuss about the Proper time ?

OK, what do you want to ask?

Hey ?

@JohnRennie, Hi John, is there a link where I can find details of coulomb law in an atom?or can you you tell in a nutshell?

@JohnRennie sorry I was stuck with an important work :)

"We call s the proper distance and T the proper time. They are basically the same thing because they differ only by a constant."

So proper time T is the quantity that becomes less to equal the distance moved by you in time ?

Hi @JohnRennie , reply to me whenever ur free , if ur familiar with the experiment of electrons and neutrons possessing properties which are put to test if they are persistent or not through "color and hardness boxes" , this experiment with various modification talks about the superposition principle , what exactly does superposition mean?
