Why we can't explain a battery and circuit a voltaic cell so that we can say flow is in battery from + to - and in circuit from -to + ; isn't it alright???
Why we make it exactly vise versa and say it's an electrolytic cell; but this cell has a battery itself which makes complexity...I'm getting crazy, please help...

In the early days they knew current only flowed one way, but they didn't know which way. So they arbitrarily said it flows from plus to minus. Later they discovered that electrons actually flow from minus to plus. They decided not to change all the books and papers, so they still teach it backwards. It doesn't cause any problems. It is one of many things that you just have to accept and get on with your work.
The real mechanism is like a row of marbles. You push on one end and the push is carried to the other end, but the marbles don't actually move much. Electric current flows at nearly the speed of light, but the electrons move only a few centimeters per second. It is only in a vacuum tube that the electrons move at significant speed.
Well i can memorize it backwards, but my problem is what happens in real; how we explain the real mechanism...
