Electronics - Voltage and Current - Discussion

Conventional Flow is considered at first before they discovered that the electrons are actually the ones moving from the negative to the positive side. Technically it is still the same and is useable for any kinds of circuits, it just depends on the perspective of the person looking at the circuit if he/she wants to use a conventional flow or current flow. But according to history, the first thought of people was the conventional flow so it came first that's why C is correct.

Also, protons cannot flow since they are located in the nucleus of an atom. Only electrons can be dislodged and flow in the form of a current.

What is the difference between conventional current and electron current ?

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.

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.

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

I think the answer is B.

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

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.

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.

Without the flow of electron how "current" comes?

Current itself means the flow of charge.
