Dear Student, 
Please find below the solution to the asked query: 
  • No, Ohm's law is not universal.
  • Ex: Ohm's law is applicable to ohmic conductors such as iron, copper etc. , but not applicable to non-ohmic conductors such as semiconductors

Hope this information will clear your doubts about Ohm's law.

 I.Ohm's law (like Hooke's law) is not universally valid. The many substances for which Ohm's law holds are called ohmic. These include good conductors like copper and aluminum, and some poor conductors under certain circumstances. Ohmic materials have a resistance R that is independent of voltage V and current
