The theories and books all said that in a circuit, electrical current flows out of the positive terminal of a battery, and returns into the negative terminal. However, the new discoveries concluded that, contrary to conventional wisdom, electrons flowed the other direction.
I would appreciate it very much. There is a convention for the technical direction of the current: positive current flows from the plus pole of a battery to the minus pole by convention. The microscopic details of conduction in a specific medium/conductor are a different thing. In some conductors, like metals, it is actually electrons that flow.
Nowadays, in general, most electronic technicians use electron flow as the direction of electrical current in a wire, and most engineers use the conventional direction of electrical current in a wire.
As above, the direction of the current is the opposite of the direction of the flow of electrons. Reactions occurring are the opposite of the reactions given by Equations 9.3.1 and 9.3.2. By definition, the cathode is the electrode which electrons flow towards, and the anode is the electrode which electrons flow away from.
The direction of electric current flow is a little difficult to understand to those who have been taught that current flows from positive to negative. There are two theories behind this phenomenon. One is the theory of conventional current and the other is the theory of actual current flow.
Maybe something like "Current flow in batteries?" Actually a current will flow if you connect a conductor to any voltage, through simple electrostatics.
Understanding the Concept of Electric Current. As long as the battery continues to produce voltage and the continuity of the electrical path isn''t broken, charge carriers will continue to flow in the circuit. ... In the second volume of this book …
