In this work, we derive the telegraphy equation from Weber's electrodynamics. This is done for conductors of different geometries. We compare our results with the ones predicted by the classical electromagnetism.In this work, we derive the telegraphy equation from Weber's electrodynamics.

Isto é feito para condutores de diversos formatos. Comparamos os resultados obtidos com os preditos pelo eletromagnetismo clássico.
