why does current flow from positive to negative

As on today, we know that electrons are negatively charged and thus, the conventional current flows in the direction opposite to the direction of electron motion. 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.

It’s two different conventions. Energy always flows from higher potential to lower potential. When physicists originally came up with their convention, they labelled protons positive and electrons negative. Isn't current just the flow of electrons? This was the convention chosen during the discovery of electricity. Positive charge carriers flow from positive to negative.

The particle responsible for electricity is the electron which has negative charge.

Conventional Current assumes that current flows out of the positive terminal, through the circuit and into the negative terminal of the source. Current is flow of electric charges , the charges could be electrons, protons, ions, holes in semiconductors etc.

Conventional direction of current is that followed by a positive charge from positive terminal to negative terminal in a circuit or its branch.
The Conflict in the Direction of Electrical Flow We had a conflict. In this case, they don’t mean protons or positrons: they’re talking about the flow of “space lacking electrons” or “electron holes” – gaps in space where there are no electrons even though there could be. He also concluded that the current flow known as the "Edison Effect" was made by electrons traveling through the vacuum. And aren't electrons negatively charged? Electron Flow is what actually happens and electrons flow out of the negative terminal, through the circuit and into the positive terminal of the source. Current is flow of electric charges, the charges could be electrons, protons, ions, holes in semiconductors etc.

;) First major mistake: believing that “electric currents are electron-flows.” Nope, wrong. Conventional direction of current is that followed by a positive charge from positive terminal to negative terminal in a circuit or its branch. Remember one thing. The Conflict in the Direction of Electrical Flow We had a conflict.

The term 'conventional current' is a singular, common, compound noun; a word for current flowing from positive to negative as opposed to electron flow where current flow is from negative to positive. Current means flow. He also concluded that the current flow known as the "Edison Effect" was made by electrons traveling through the vacuum. Beware: this topic is full of mistakes and wrong explanations. what direction does the current and or electrons flow in a circuit ? is it positive to negative or negative to positive? " The problem is, electrons are negatively charged, so they want to get away from the-ve and go to the +ve. This choice of direction is purely conventional. Current flows from the positive (+ve) terminal of the battery to the negative (-ve). When discussing positive to negative flow, electrical engineers will sometimes discuss positively charged particles flowing. They were wrong! A flow of positive charges gives the same electric current, and has the same effect in a circuit, as an equal flow of negative charges in the opposite direction. Electric current means flow of electric charges Now there are two kind of charges.
If those are both the case, does that not mean that electrons would be attracted to anything positive, and therefore current would flow from negative to positive? Beware! Since current can be the flow of either positive or negative charges, or both, a convention is needed for the direction of current that is independent of the type of charge carriers. An electric current is viewed as flow of positive charges from the positive terminal to the negative terminal. In a battery, the negative terminal has an excess no. The flow of electric current occurs because we have a high potential of electrons gathered at the positive terminal and a low potential of electrons at the negative terminal. This is called conventional current flow.
