why the flow of current is taken from positive to negative of a cell even though electrons are flowing in opp?

Answer 1

Conveontionally, it was thought that the positive charge flows and so the name "conventional current". However, it was then discovered that electrons, the negative charge, was the one that flows from the negative to the positive and hence the "electron current" was introduced.

Of course, since all formulae and other concepts are based on/explained by the conventional current, it is still widely used today in Physics. Unless we are looking at electrolysis and other topics within Chemistry, the conventional is still the convention.

Answer 2

That's just a convention .Earlier It was thought that positive charges conduct electricity and so it was taken as convention that current flows from positive to negative end.However later it was discovered it was electrons actually.But it was decided to continue with the old convention as most of scientific literature available was based on this convention.
Note that this convention doesn't make any difference to the way we analyse the circuits.

Answer 3

It's what we call "Conventional Current Flow" as opposed to electron flow..... Basically it saves us rewriting the theory of electricity based on changed understanding... much easier to use "convention".

Answer 4

when there is positive charge at one end, then the electrons rush in to make the equilibrium... that means that charge is flowing in the opposite direction ei, from positive to negative.. that is the current..

Answer 5

which current u r talkin bot. it is conventional current which is taken from +ve to -ve terminal but electronic current is taken from -ve to +ve end
