even though it's the electrons that move from negative terminal of the battery and gets move along the external circuit and finally enters the positive terminal of the battery and due to battery force move again to its negative part, so what should i consider, can anyone clear it ?

$\begingroup$ What do you mean by “so what should I consider ?”. It’s unclear what you are asking $\endgroup$– Bob DCommented Sep 2, 2020 at 11:45

$\begingroup$ it actually means "what should i consider" that is what i should take $\endgroup$– matte geekCommented Sep 3, 2020 at 4:02

I hope I understand your question correctly.
This is all caused by the fact that the "positive" and "negative" labels were assigned long before the electron was discovered.
Back in the early 1700s it was discovered that there were two kinds of static electricity, depending on the materials used to generate them. Initially it was assumed there were 2 different kinds of "electric fluids". Benjamin Franklin first proposed that the charges were caused by an excess or absence of a single fluid. He arbitrarily labelled the charge carrier as "positive". During the same period, batteries were developed and arbitrarily assigned positive and negative terminals.
Then, in 1897, J.J. Thomson discovered that electricity was carried by a "particle". He was found that this particle actually has a negative charge.
To this day, circuit analysis keeps using the old conventions and uses a hypothetical positive current - while keeping in mind that electrons actually flow the other way. In most cases this does not matter at all to the analysis.
