It's basically an accident. Current flow was defined before science had figured out electron flow.
AnswerBefore the structure of the atom was understood, scientists such as Benjamin Franklin believed that an electric current was a flow of some sort of mysterious 'fluid' that moved from an area of high pressure to an area of low pressure. The high pressure was considered to be 'positive' pressure and the low pressure was considered to be 'negative pressure'. So, for many years, current was believed to travel from positive to negative.
Even though we now know that ( in metallic conductors, anyway) that current is a flow of free electrons from negative to positive, for some weird reason many textbooks still show current as flowing from positive to negative! To differentiate between the two current directions, we use the terms 'electron flow', and 'conventional (or 'Franklinian') flow'.

A backflow is a flow of a liquid in a direction opposite to that which is intended.
in only one direction
The electrical current comes into the bulb from the metal side,flow through the filament ,and out the tip.
water
the directions are opposite to each other
the directions are opposite to each other
The "flow of current" is considered to be in the opposite direction.
can't as there is only one: they are in opposite directions. conventional current flow was defined arbitrarily before the discovery of electrons to permit mathematical analysis of circuits. electron current flow was defined after the discovery of electrons.
Electron movement is referred to as electric current. When electrons flow through a conductor, such as a wire, they carry electrical energy from one point to another. The direction of current flow is opposite to the direction of electron movement.
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.
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 direction of current flow is defined as the direction positive charge carriers would flow, which is opposite to the actual movement of electrons (negative charge carriers) in a wire. Electrons flow from the negative terminal of a power source to the positive terminal, while conventional current flows from the positive terminal to the negative terminal.
Anthony count Alternating Current - electrons that flow alternately in opposite directions constitute an Alternating current.
1.6x10^19 amperes is the amount of current that a flow of an electron will contain.
always current flow from the opposite direction of electron
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.
