When discussing electrical current, DC stands for Direct Current (a current where the electron flow in the wires goes only one way)
When we consider electron flow, we think of moving electrons. The electron has a negative charge. This model of current flow, the electron current flow model, follows the movement of those negative charges.As a contrast, we might consider what is called conventional current flow. And that the model of current involves the movement of charges with a positive polarity.
A current consisting of charges that flow only in one direction is called direct current (DC). In DC, electrons flow continuously in one direction from the negative to the positive terminal of a power source.
Answerits lightning, for a more simple answer......electric current flow is the movement of charges. Most often, however, we consider electric current flow to be moving electrons, or electron current flow.We most often use the term electric current flow to refer to the moving electrons, the flow of which is measured in amperes.Earlier scientists, before the discovery of electron, do believe that current flows right from positive terminal to the negative. This is known as conventional current flow.So electron flow is always opposite the direction of conventional current.
The direction of current due to flow of electrons is opposite to the direction of conventional current. This is because electrons have a negative charge, so when they flow in a wire, they are actually moving in the opposite direction to the current flow defined by convention.
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.
1.6x10^19 amperes is the amount of current that a flow of an electron will contain.

A unidirectional flow of electrons is known as direct current (DC). In a DC circuit, the electrons flow in a constant direction from the negative terminal to the positive terminal of the voltage source.
When we consider electron flow, we think of moving electrons. The electron has a negative charge. This model of current flow, the electron current flow model, follows the movement of those negative charges.As a contrast, we might consider what is called conventional current flow. And that the model of current involves the movement of charges with a positive polarity.
The electrons flows from negative to positive and then positive to negative.The pole of the flow of electron changes at a time interval.This is called alternating current (AC).
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).
The current flow is from positive to negative whereas electron flow is from negative to positive.
P to N
The "flow of current" is considered to be in the opposite direction.
A current consisting of charges that flow only in one direction is called direct current (DC). In DC, electrons flow continuously in one direction from the negative to the positive terminal of a power source.
Electrons are in random motion in a material, such that there is no resultant electron movement. Hence a material has no current flow by its own. Only the directed flow of this charge in a direction, will results in current. when we provide sufficient energy (for example by mean of applied potential difference ) the net motion of the electron gives rise to the current flow.
