Difference between charge of electron and proton?

Click For Summary

Discussion Overview

The discussion revolves around the perceived difference between the charges of electrons and protons. Participants explore the implications of this idea and seek clarification on the concept of electric charge in relation to fundamental particles.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant suggests that it seems logical for electrons and protons to have equal but opposite charges, questioning why there might be a small difference.
  • Another participant expresses confusion, asking for clarification on what difference is being referenced.
  • A third participant questions the validity of the claim about a difference in charge, indicating that they have not encountered this information before.
  • A participant recounts a conversation with a teacher who suggested that the charges are not exactly equal, expressing uncertainty about the details and indicating a desire to clarify this misunderstanding.
  • The same participant reflects on the notion that the elementary charge "e" is a fundamental quantity, implying that if protons had a different charge, it would challenge this understanding.
  • Another participant encourages the original poster to seek clarification from the teacher to resolve the confusion.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the existence of a difference in charge between electrons and protons, with some expressing skepticism about the claim while others are uncertain and seek clarification.

Contextual Notes

There are unresolved questions regarding the validity of the claim about a difference in charge, and the discussion reflects a lack of clarity on the definitions and measurements of electric charge.

Hey guys,

I understand it would be logical for electron and proton to have the same charge but with opposite signs... Why then is there a smalll difference between their charges?

Thank you

What difference?

That's news to me. Where did you read this?
 
I heard from a teacher at University, he said something like "let's suppose that the electron and the proton have exactly the opposite charge even though that's not exactly true". I didn't have the chance to ask him which was the difference and I didn't want to wait until Monday to know. I also heard something similar a few weeks ago but now I'm searching on the internet and my textbooks and i can't find any difference in the measures of charges... Maybe i just misundertood something.
It seemed really weird to me cause i thought that "e" was the quantum of electric charge (without thinking of quarks), and if the proton had some similar but slightly different charge then that wouldn't be true.

If nobody has heard about this maybe I just misunderstood my teacher... I'll ask him to see if i can solve the misunderstanding.

Thank you for your time and sorry for my bad english.
 
Your English is fine.
I think it would be best, as you suggested, to talk to the teacher to find out what was misunderstood.
