  2. Dimensionless scalar ratio without base units
  3. Arbitrary empirical units without dimensional consistency
  4. Gravitational units only
Answer
Standard SI derived units defined by international physical constants for Alternating Current

The correct answer is Standard SI derived units defined by international physical constants for Alternating Current — The dimensional formula confirms consistency across both sides of the field equations.

Step-by-step solution

  1. Dimensional analysis converts base SI quantities (M, L, T, A) into the derived unit for Alternating Current.
  2. The dimensional formula confirms consistency across both sides of the field equations.
