Electronics - Voltage and Current - Discussion

No clear explanations. First explain what is conventional current and electron current.

Conventional current flow refers to a flow of positive charges. It is a kind of ficticious current. If - as is often the case - the real current is an electron flow (negative charges) , then the conventional flow is a current in the opposite direction as the electron movements, since this would have the same effect (for example on the magnetic field, or on conservation of charge).

I can't understand the question and answer also?

Conventional Current assumes that current flows out of the positive terminal, through the circuit and into the negative terminal of the source. This was the convention chosen during the discovery of electricity. They were wrong!

Electron Flow is what actually happens and electrons flow out of the negative terminal, through the circuit and into the positive terminal of the source.

Both Conventional Current and Electron Flow are used by industry. Many textbooks are available in both Electron Flow and Conventional Current formats.

In fact, it makes no difference which way current is flowing as long as it is used consistently. The direction of current flow does not affect what the current does.

In general, two year technical programs and highschool Physics use Electron Flow.

But three year technician and university engineering programs still use Conventional Current. Certain symbols (ex. diodes and transistors) and rules (ex. Right hand rules for electromagnets) were created using Conventional Current. Changing from Conventional Current to Electron Flow would cause a degree of confusion for old and new students and errors would occur, so Conventional Current was kept to ensure there was no confusion.

Throughout this course, Conventional Current is used. Therefore always assume current flows out of the positive terminal of the source.

IN this question it is asked which current flow came first
it is about it time of invention or launching not its speed

so the answer is conventional flow of current is used fist in curcuit anlaysis

The conventional current flow method only at first when they discovered the electricity but they were wrong. But now we are using electron flow only in current era.

Answer should be Protons move in conventional current flow & it is opposit to the electron current flow direction.

Still I can't understand, what is conventional current and why conventional current flow came first. Please explain me in a simple way.

Please tell me, what is mean by conventional current ?

Direction in which an electric current is considered to flow in a circuit. By convention, the direction is that in which positive-charge carriers would flow - from the positive terminal of a cell to its negative terminal. It is opposite in direction to the flow of electrons. In circuit diagrams, the arrows shown on symbols for components such as diodes and transistors point in the direction of conventional current flow.
