SUMMARY

The true definition of electric charge is fundamentally linked to the elementary charge, quantified as 6.24150962915265 × 10^18 elementary charges per coulomb. Electric charge serves as a measure of the electrical participation of matter, where particles with zero charge do not engage in electrical interactions. Additionally, in Gaussian units, electric charge is defined in relation to mass, length, and time, with specific units of mass^(1/2) × length^(3/2) × time^(-1).

PREREQUISITES
  • Understanding of elementary charge and its significance in physics.
  • Familiarity with the concept of coulombs as a unit of electric charge.
  • Basic knowledge of Gaussian units and their application in electromagnetism.
  • Conceptual grasp of the relationship between charge, mass, length, and time.
NEXT STEPS
  • Research the implications of elementary charge in quantum mechanics.
  • Study the relationship between electric charge and electromagnetic fields.
  • Explore the historical development of the concept of electric charge in physics.
  • Investigate the role of Gaussian units in modern physics and their applications.
USEFUL FOR

Physicists, electrical engineers, students of physics, and anyone interested in the foundational concepts of electromagnetism and charge properties.

what is the actual definition of electric charge ?
 
Physics news on Phys.org
Wiki article:

an alternative (not yet official) definition of the coulomb. A coulomb is then equal to exactly 6.24150962915265 × 10^18 elementary charges.

not of the unit of the charge but of elementry charge

Hi.
Force by electric field / electric field.
Regards.
 
Charge is the measure of electrical participation of matter. A particle with 0 charge does not interact directly in electrical events.

What is the actual definition of mass? What is the actual definition of temperature?

All three represent properties of materials. The origin of the properties is not known, but it is possible to measure and compare different materials based on those three (and most likely other) properties.
 
Elementary charge is measured (implicitly through experiments), not defined.
 
Fwiw, recently another member here, clem, pointed out that in Gaussian units, charge is actually defined in terms of mass, length and time, and has units of mass(in grams)^1/2 x length (in cm)^3/2 x time (in seconds)^-1.
