Question

State and explain Ohm's law.

Answer 1

Statement : The electric current passing through the conductor is directly proportional to the potential difference across its ends provided temperature and other physical conditions remain constant.
Explanation : If current $I$ is flowing through the conductor and let $V$ be the potential difference between the ends of the conductor,
$V\propto I$ or $I\propto V\Rightarrow V=IR$.
