The term "conventional flow" is usually used specifically for electricity, not for any kind of energy. If the current consists of electrons, then, if the electrons move in one direction, the conventional flow (a ficticious flow of positive charge) flows in the opposite direction. If the electric flow consists of positive charges, then the conventional flow and the physical, or real, flow, are in the same direction. An electron current is the most common case, though.

In which direction does conventional current flow?
Conventional current is defined as the flow of positive charges. If the actual flow is negative particles (as is often the case; usually electrons), the conventional current flows in the direction opposite to the electron flow.
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.
Do electrons travel in the same direction in a circuit?
In a circuit, electrons flow from the negative terminal to the positive terminal of the voltage source (such as a battery). This flow of electrons is opposite to the conventional current direction, which is from positive to negative. So, while electrons themselves move in one direction, the conventional current moves in the opposite direction.
How many directions does energy flow?
Energy can flow in any direction based on the system in question. It can move from high energy to low energy areas, between different forms (such as from heat to mechanical energy), or be stored for later use.
Why do current and electrons move in opposite directions?
Current is defined as the flow of positive charge, which historically was thought to be the flow of protons. However, it was later discovered that it is actually the movement of electrons that constitutes electric current. Electrons have a negative charge, so when they move in one direction, the conventional current (positive charge) appears to move in the opposite direction.
What is the difference between electron flow and conventional current?
We all know that, in metal conductors (but not in other conducting media), free electrons slowly drift from the negative end of the conductor to the positive (or 'less negative') end of the conductor. But before anyone knew about atoms, an electric current was thought to be the flow of some sort of 'fluid' from a higher pressure (i.e. positive pressure) to a lower pressure (i.e. a negative pressure) -as suggested by Benjamin Franklin. This error was reinforced by Michael Faraday as a result from his experiments in electrolysis.So 'electron flow' (- to +) describes what is actuallyhappening in a metal conductor, whereas 'conventional flow' (+ to -) is, to put it simply, an error!Unfortunately, because so many 'rules' that relate current direction to the direction of magnetic fields and electric fields were based on conventional flow, many textbooks have found it convenient to stick with conventional flow.
What reverses the normal flow of thermal energy?
A heat pump can reverse the normal flow of thermal energy by transferring heat from a cooler space to a warmer space, using electricity to move heat in the opposite direction it naturally flows.
Why doesn't all current move in the same direction?
Not all current flows in the same direction because electric energy does not follow the circular flow of electricity which results to direct and alternate current.
Why flow of current from cathode to anode still the flow of electrons is from cathode to anode?
The direction of current, according to convention, is the direction opposite the direction of electron flow. Remember that the anode is where oxidation occurs, so electrons are lost by the anode. These electrons then move from the anode, to the cathode by a wire that usually connects the two compartments. To reiterate, the electrons flow from the anode (site of oxidation) to the cathode (site of reduction). Because electrons flow from anode to cathode, by convention the direction of current is from cathode to anode (the direction opposite the flow of electrons). Hope this helps!
What is real current flow?
Real current refers to an analysis of the charges that actually flow - for example electrons in a metal - as opposed to the "conventional current", that uses a ficticious current of positive charges. If the electrons move to the left, the "conventional current" moves to the right. If positive charges (e.g. ions) move to the right, the conventional current also is to the right.
How is the electron flow different from conventional current?
The conventional current direction is the direction in which a positive charge would move. Since electrons are negatively charged, the electrons move (in average) in the opposite direction.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, but it had nothing to do with 'a flow of positive charge carriers' because no-one then knew about 'charge carriers'.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'.
How convenional current flow negative to positive?
A conventional current is defined as the flow of positive charges. If - as is often the case - the real particles have a negative charge, and they move, say, from left to right, then the conventional current flows from right to left.
