Who (and Why) started the “electrons are negative, protons are positive” convention? [duplicate]

For some reason everyone labels electrons using a minus sign and protons using a positive sign, even though the opposite seems more intuitive: Who started the convention that electrons should be "...

What proved Conventional sense wrong?

What fact proved for the first time that the conventional sense of current was wrong? And when it did happen? As a corollary of this question, why do we say that electrons have negative charge? Is it ...

What would have happened if electron was considered positive?

We always keep on telling that current flows opposite to electron, since electron is negatively charged. And old people didn't knew, that it is electron which actually flows.. So, now if we correct ...

Positive test charge

Protons have positive charge on them. Protons aren't mobile. So how can a positive test charge move from the negative terminal of a cell to the positive terminal and gain electric potential energy? ...

Please tell me that why aren't we discarding the conventional flow of current despite not being in sync with principle of potential difference [duplicate]

electric current flows from higher potential area (negative terminal) to lower potential area (positive terminal).this clearly indicates that electric flow (flow of electrons) takes place from ...

Why are electrons negative? [duplicate]

By my understanding their charge could have been called positive, and the charge of the proton and positron called negative. What are the historical reasons for this?

IF electrons flow in opposite direction to the electric current then what constitutes the current?

If electrons flow to the opposite direction to the electric current and the protons do not move instead they create the current, then what actually flows in the electric current? Since current is flow ...

Why are electrons negetively charged? [duplicate]

Why have we assigned a negative charge to electrons (and positive for protons)? I feel it would be easier if electrons were positive (thereby, protons negative)- electrons would flow in the direction ...

Negative ampere and graphical convention

Since only electron's flow in electricity and electrons have negative charge, then why we don't say —1amps (—1C/s)? Secondly, as conventional way we write down independent variable in $x$ axis and ...

Why is it said that electric current always flow from higher potential to lower potential?

Why is it said that electric current always flow from higher potential to lower potential? It is said that current flows from positive terminal to negative terminal, but it is actually the negative ...

Why aren't electrons positively charged? [duplicate]

For the study of electric circuits, it seems like it would have made more sense to establish that electrons carry a positive charge, and protons a negative one. That way, arrows representing current ...

Benefits of the sign convention for electrons?

Benjamin Franklin considered electrons to be positive, but J.J. Thompson considered them negative. We obviously went with J.J. Thompson's convention. Why? What were the benefits of moving to J.J. ...

Why do current and electrons flow in opposite directions? [duplicate]

In representing an electric circuit, we would draw the sense of the current from the positive to the negative pole and the electrons from the negative to the positive . But as I know electrons' motion ...
