In metal conductors, an electric current is a drift of free electrons from a negative to positive. Period! 'Conventional' current (positive to negative) is, as its name indicates, nothing more than a convention -based on an assumption made before the true nature of electricity was determined. In other words, it doesn't exist! So no experiment can 'prove' that conventional current exists because it doesn't exist!
The direction of conventional current was based on the assumption, by the likes of Benjamin Frankin, who assumed that an electric current was some sort of fluid which, of course, would flow from a high (positive) pressure to a low (negative) pressure. The discovery of the structure of the atom confirmed that a current (a flow of electrons, in metal conductors) flowed from negative to positive.
Think of it this way. When you look at a led display in a waiting room ('take a ticket'), are the illuminated leds moving to the right, or are the unilluminated leds moving to the left? Think of the illuminated leds as electron flow, and the unilluminated leds as conventional flow.

What flow is equal to and opposite of electron flow?
The "flow of current" is considered to be in the opposite direction.
What current flows in one direction then the opposite direction?
AC, Alternating Current.
How left-hand rule is used for finding direction of force of current carrying wire when electron is moving from east to west?
what is the direction of motion of current carrying wire when electron is moving from east to west
The expression alternating current refers to which form of energy?
Alternating current is a flow of electrical energy in which the direction of electron flow reverses periodically. The mains electricity in your house is likely Alternating Current. The other form is Direct Current, where the direction of electron flow is in one direction only. Such as the flow from the batteries in your flashlight.
When an electric current flows through a long conductor how does each free electron moves?
The individual electrons will move back and forth, as they do when there is no current. You would have to do very careful statistics to notice that there are slightly more electrons moving in one direction than in the other: the drift velocity (average velocity due to current) of the electrons is typically a fraction of a millimeter per second.
What flow is equal to and opposite of electron flow?
The "flow of current" is considered to be in the opposite direction.
Why the current is flowing in opposite direction in cables?
the charge of the electron is negative
What is the relationship between the direction of current and direction of electron flow in a current carrying wire?
the directions are opposite to each other
What is the relationship between the direction of current and the direction of electron flow in a current carrying wire?
the directions are opposite to each other
What is the direction of the force on an electron that is moving alongside a wire that is carrying a current in the opposite direction?
90 degree
When electrons are moving from negative pole to positive pole in the circuit then current in the circuit will be moving in which direction?
always current flow from the opposite direction of electron
What is the relationship between the direction of current and direction of electron flow in a current-carrying wire?
because the current is actually the flow of electrons.
What is the conventional current flow?
Conventional current flow is the flow of positive charges, or the equivalent flow of positive charges. That is, if what flows is really negative charges (for example, an electron), which flow in one direction, the "conventional current" flows in the opposite direction.
What current flows in one direction then the opposite direction?
AC, Alternating Current.
Difference between electron flow and conventional 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).
In what circuit does the current flow in one direction and then in the opposite direction?
on a three way switch.alternating current.
How can you create an electron source for an experiment?
by creating a current flowing circuit
