SUMMARY

The discussion centers on the dimensional representation of the Coulomb (C) in the International System of Units (SI) without referencing amperes (A). Participants confirm that the Coulomb is fundamentally defined as C = A*s, and that it cannot be expressed solely in terms of the base units of mass (kg), length (m), and time (s). The consensus is that the Ampere is a base unit by definition, and thus cannot be derived from other base units. The dimensional analysis reveals that Coulomb has dimensions of [M]^(1/2) * [L]^(3/2) * [T]^-1 when considering its relationship to force and charge.

PREREQUISITES
  • Understanding of SI base units: meter (m), kilogram (kg), second (s)
  • Familiarity with dimensional analysis techniques
  • Knowledge of electrical units, specifically Coulombs and Amperes
  • Basic grasp of physics concepts related to electromagnetism
NEXT STEPS
  • Research the dimensional analysis of Coulomb's law and its implications
  • Explore the differences between SI and cgs (centimeter-gram-second) units
  • Study the definitions and implications of base units in the SI system
  • Investigate the historical context and evolution of unit definitions in physics
USEFUL FOR

Physicists, electrical engineers, students studying electromagnetism, and anyone interested in the foundations of measurement units in science.

Yes, but the argument is more than two years old. PF discourages reviving old threads (a practice which is called necro-posting.)

You can, however, start your own thread, and refer to another thread, if you wish.

No, it doesn't. See the official BIPM page: http://www.bipm.org/en/measurement-units/base-units.html

Yes. Thread closed.
