What Is The Basic Principle Of Ohm's Law?

Ohm’s law describes the relation between electric current and potential difference.

  • It states that the current flowing through most of the conductors is directly proportional to the voltage applied to it.
  • Ohm’s law is only true if temperature and other physical factors remain constant.
