It becomes positive...
That is a good way to run the cell down quickly. Electrons are negatively charged so they always move from the positive terminal towards the negative. Each electron carries a charge of 1.602 x 10-19 coulombs so 1 coulomb (1 amp for 1 second) carries 6.24 x 1018 electrons.
Strangely there is two directions it is said to flow. The first and wrong is conventional current that is positive to negative. WRONG. Several hundred years ago people guest Electron current is the direction it actually goes in. This is negative to positive.
Anode is positive electrode which attracts the negative anions while cathode is the negative electrode which attracts the positive cations during electrolysis.
This is because the conventional definition of a current flow is "the flow of POSITIVE charges" (from positive to negative terminal). However, positive charges in conductor do not move. It is only the electrons that are mobile. Hence the electrons will move towards the positive terminal, hence it is in the opposite direction of conventional current.See related links below.Additional AnswerWhen Benjamin Franklin was theorising about the nature of an electric current (long before the discovery of atoms), he thought that it was some sort of 'fluid' that flowed from an area of high pressure, which he labelled as 'positive', to an area of low pressure, which he labelled as 'negative'. Although we know that, in metal conductor at least, an electric current is a flow of negative charges (electrons) that flow from negative to positive, many (but by no means all) textbooks still use Franklin's current direction which is called 'Franklinian Flow' or, more commonly, 'Conventional Flow'.The reason for still using conventional flow seems rather odd, as there is no real advantage of continuing to do so.
Electronic flow is true. Conventional flow was thought to have positive charges flowing from the + terminal to the - terminal. This was before we knew that it is actually the electrons which flow, and the positive charges cannot move out of their atomic nuclei. Now that electrons have been detected, and protons are known to stay within the nucleus unless a nuclear reaction takes place, we know that it is the electrons that flow from the - terminal to the + terminal. This is known as electronic flow.
Electrons have a negative charge. For that reason, electrons will always flow in the opposite direction of the current, which flows from positive to negative. Electrons will therefore move from a negative terminal to a positive terminal when we look at the load on a cell. Within the cell, the electrons will flow from the positive terminal to the negative terminal.
Yes, electrons flow from the negative terminal to the positive terminal in a circuit. This is because electrons are negatively charged particles, and they are attracted to the positive terminal.
the positive side, the negative side is usually just a ground
The shortage of electrons exists at the positive terminal of a dry cell. These positive terminals attract electrons, creating a flow of current from the negative terminal to the positive terminal through an external circuit.
It is called the positive + terminal or post, just like you list. Electrons flow for the negative - to the + terminal contrary to popular belief.Another AnswerAs electrons flow through the external circuit from anode (negative terminal) to the cathode (positive terminal) , then the answer is 'cathode'.
Electrons are pushed out from the negative terminal of a battery towards the positive terminal when a circuit is connected.

Electrons are negatively-charged particles that flow out from the negative terminal and into the positive terminal of a battery. It was once assumed that moving particles had a positivecharge, and so this conventional current flow set the original arrow direction, still shown on diodes and junction transistors.
Outside the battery:The path for conventional current goes from the positive terminal (+, usually a red wire) to the negative terminal (−, usually a black wire).A wire's electrons flow from the negative (−) terminal to the positive (+) terminal.Since the current forms a continuous a loop in the same direction, the direction inside the battery is "backwards".Inside the battery:Conventional current flows from the negative (−) terminal to the positive (+) terminal.Positive ions flow from the negative (−) terminal to the positive (+) terminal.Negative ions flow from the positive(+) terminal to the negative (−) terminalConventional current assumes that all flowing charges are positive. It simplifies the situation because it hides the more complicated electrons, positive ions, and negative ions.
If we go for the diagramatic representation then battery positive is represented by the long terminal and battery negative is represented by the short terminal then the direction of the current is given by an arrow from positive terminal to negative terminal (Therotically electrons flow from negative to positive but we represent current flow from positive to negative. This is the sign convention )
Electrons flow from the negative terminal to the positive terminal of a battery due to the potential difference created between the terminals. This movement of electrons completes the circuit and allows for the continuous flow of current, enabling the battery to provide power to electrical devices.
Electrons flow from the negative terminal to the positive. Conventional current or simply current, behaves as if positive charge carriers cause current flow. Conventional current flows from the positive terminal to the negative
