Electron flow and electric field question [duplicate]

My understanding is that the electric field lines of a proton goes outwards and an electron goes inwards, are theses properties the same for electron flow or is just for conventional current? I think ...

Can the signs of charge of electron and proton be reversed? [duplicate]

I was thinking that the electron, proton, neutron etc. are human given names to some particles. So, are the signs, positive of proton and negative of electron, given just to show their opposite ...

Confusion about electron flow and current

So, I learned in class that current is defined as positive charges moving from south to north. However, in all reality, the negative charges are moving, but the convention of positive to negative wors ...

Effect of a magnetic field on cathode rays in a cathode ray tube

My question is regarding the direction in which cathode rays bend in a magnetic field. My book states that : When only electric field is applied, the electrons deviate from their path and hit ...

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 ...

Are electric sources and sinks symmetrical?

When discussing sources and sinks for the property of divergence of electric fields, why is the positive polarity uniquely selected as a source and the other a sink? Aren't they both sources and sinks ...

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 ...
