The fact that the electron has a negative charge and the proton has a positive charge is due to a convention established byBenjamin Franklin. Would there have been any significant consequences if Franklin had chosen the opposite convention? Isthere any advantage to naming charges plus and minus as opposed to, say, A and B?
