what is conventional & electronic current?

Answer 1

Conventional current is the 'flow' of positive charges in a conductor.

Electronic current is the physical 'flow' of electrons in the outer valence band of the conductor atoms.

Even though it is actually negative charged electrons that carry current in a conductor and they flow from the negative terminal of a voltage source (i.e. battery) to the positive terminal of the source, we say by convention that current flows from positive to negative. That's why it's called conventional current.

This convention makes all of the mathematical calculations (Farday's law, Gauss' law, Ohms law, the direction of the force produced by current in a wire, the proper phase of a guitar pickup, microphone or speaker, etc. etc. ) all come out properly.

Even electrons themselves don't 'flow' at the speed of light within the conductor itself. They have a drift velocity that is much less than the speed of light (speed of information) in the conductor as they move in random motion towards the positive terminal of the voltage source.

Conventional current always flows at the speed of light in the conductor (which is dictated by the relative permittivity and permeability of the conductor).

Answer 2

Think of negatively charged object as having an excess of electrons and a positively charged object having a difficiency of electrons or "holes".Electrons flow through a conductor( current flow) measured in Amperes to fill up the holes to neutralize the two objects.The difference in the potential or pressure is Electromotive force and is measured in Volts

Coventional current flows from negative to positive like stated above

Some current also flows positive to negative in a battery because the batery has some resistance

Answer 3

Electron current is a flow of electrons from negative to positive. Conventional current is a flow of "holes" from positive to negative.

Answer 4

Are you talking about conventional current flow, aka "hole flow" versus electron current flow? You can look at current flow in either of 2 ways - either as a stream of electrons moving from one atom to the next, negative to positive, or as the flow of the empty spots for an electron going from positive to negative. Both views are equally valid, choose your point of view according to convenience. I use hole flow most often as I trace through a circuit, especially those whose supply voltage is positive compared to circuit common.

Answer 5

Maybe conventional meaning analog and electronic meaning digital (either around 0V or around 5V)

Answer 6

I think you are talking about the same thing using two different names.
