Electronics - Voltage and Current - Discussion

Mass is inversely proportional to the speed. Mass of a proton is 1836 times of an electron mass. So the speed of electron > speed of proton. Electron current come first than conventional current (i.e Current for proton).

Without the flow of electron how "current" comes?

Current itself means the flow of charge.

In the question, they mentioned the discovery of the current flow.

So the conventional flow of electrons was assumed by the scientist first and then they were proved wrong and then they realized that current actually flows in the electron flow pattern.

To find the conventional current flow, first you must go to electric current defination in one word " the flow of electrons or charge" is called an electric current.

That's why conventional current flow first.

Electron flow-ve to +ve and conventional current flow +ve to - ve terminal.

I think the answer is B.

Convetional flow follows the flow of positive charge source. While the electron flow is the real movement of electrons, which is negative.

According to the law of conservation of energy.

Energy always flows from higher to lower so in electrical circuit current is shown from positive terminal of the source to the negative terminal which is called as conventional current.

But actually, in circuits ELECTRONS are moving from negative terminal to positive terminal which is called electron current.

We can agree with that they might find conventional current first in history so it can be the answer.

Conventional: Proton will have excess +ve charge, so charges will flow from +ve to -ve.

Electron flow: Electron will have excess -ve electron so, -ve charges will flow from -ve to +ve.

Both concepts are about current flow but in the different or opposite directions.

I think the scientist found the conventional current flow, that's why ANSWER is conventional current came first.

What is the difference between conventional current and electron current ?
