Leonard Wiechert Potential: Coulomb Law & Lorentz Transforms

Click For Summary
SUMMARY

The discussion clarifies that the Lienard-Wiechert potentials do not always yield the same results as the Coulomb law combined with Lorentz transformations. The Coulomb law and Lorentz transformations are applicable only when a particle moves at a constant velocity, simplifying calculations in this specific scenario. In cases of varying velocities, the Lienard-Wiechert potentials must be used to obtain accurate results.

Do the lienard wiechert potentials always give the same result as coulumb law+lorentz transformations?

Of course not. The Coulomb law+Lorentz transformations only works if the particle moves with constant velocity. Of course, this is quite a lot easier to calculate for this special case, but otherwise you need the Lienard Wiechert potentials.
