Understanding Electric Charge: Is it Just Electrons?

Click For Summary
SUMMARY

The discussion clarifies that electric charge is not solely comprised of electrons. A coulomb represents the charge equivalent to approximately 6 x 1018 elementary charges, which can include both negative charges (electrons) and positive charges (protons). The definition of a coulomb predates the discovery of electrons, indicating that electric charge encompasses a broader range of charged particles. Modern physics recognizes various particles that interact with electromagnetic fields, expanding the understanding of electric charge beyond just electrons.

PREREQUISITES
  • Understanding of basic physics concepts, particularly electric charge.
  • Familiarity with the definition and significance of the coulomb.
  • Knowledge of elementary particles, including electrons and protons.
  • Basic grasp of electromagnetic fields and their interactions.
NEXT STEPS
  • Research the properties and roles of elementary particles in electric charge.
  • Explore the historical context of the coulomb and its definition.
  • Study the interactions of charged particles with electromagnetic fields.
  • Learn about the family of particles associated with electric charge in modern physics.
USEFUL FOR

This discussion is beneficial for physics students, educators, and anyone interested in deepening their understanding of electric charge and its fundamental principles in modern physics.

I was reading my physics books. And then a question came across my mind.
Now here the the definition of coulomb. Electric charge measured in units of coulombs. It takes about 6*10^18 electrons.

So the question is did the electric charge only consists of electrons.

Any charge carrier/charged particle.

No, it doesn't have to be electrons. A Coulomb equals the magnitude of the charge on that many elementary charges, which may be negative (like electrons) or positive (like protons).
 
When the unit is defined, the electrons were not even discovered. Therefore, it highly likely not. In fact, in modern physics, electric charges are associated with particles that interact with EM fields which have a whole family of them.
