Question

in an electric circuit the direction of electric current is taken positive but the direction of the flow of electrons is taken negative. Why?

Answer 1

As per general convention the flow of current is opposite to the flow of electron.

Regarding flow of positive ion, its solely a hypothetical concept because there is nothing as positive that flow, its just lack of electron.

So better to understand in the language if electron flow only.
