Electronics - Voltage and Current - Discussion

@Rathore.

Here the question is not about flow of current. Its about concept, I mean which concept first propose to explain the flow of current in a circuit.

Why firstly convention current flow in circuit ?

Please give proper reason.

What is conventional current?

Thank you Gdk.

Conventional current is due to the migration of holes (i. E flow of protons). Hole is nothing but proton, hole forms due to the lose of electron. And this current flows in opposite direction to the electron current.

Yes @manikanta my explanation is very near to you.

coventional current= protan flow
electron current = electron flow

Electron weight is about 1/1800th weight of proton's weight.
so electron flow will be faster than the protons flow.

and the present elctronic era is considering only electronic corrent...
So my answer is electronic current comes first..
Answer should be "a"

Conventional current means protons flow. But electrons flow is much much greater the the protons. So electrons move faster than conventional current. But answer is reverse. Can any one explain it. Please.

Whatever we studied in B-Tech we always talking about current like what is the direction of current, where current is flowing etc. We all are habitual to talking like this that the "flow of current". But fact is that current never flows it is the electron which flows and some new school students are teaching in this way they don't use current flow. They use where electron is flowing, what is the direction of electron flow. This is the modern approch and came later. Thats why answer is C.

I'm clarified by gdk. Thank you!

First electrons flow always negative to positive and conventional current flow positive negative to.

Then A is the answer.
