Covariant form of equation of Continuity,4 Current density |Part 11 Four vectors,Relativity Physics|

[@RashidFaisalRashid]

Derive the continuity equation above, in a non-covariant notation (just as we did for the Schrödinger equation). Now derive it using a covariant notation Can you ask this question please?

Whether Rho is probability density or charge density

[@jacobvandijk6525]

If I call J a current density, then I would call rho a charge density (0:34).
