Question

How can we prove that Potential difference $\left(v\right)=$ Current$\left(I\right)\times$Resistance$\left(R\right)$?

Answer 1

Ohm's Law Explanation:

Ohm's Law states that “at a constant temperature, the current $\left(I\right)$ flowing through a conductor is directly proportional to the potential difference $\left(v\right)$ across this conductor.”

$\therefore v\propto I$

Assuming $R$ to be a constant of proportionality, we get

$v=I\times R$

where $R$ is termed as the resistance opposing the amount of flow of current inside the conductor.

Hence, the given relation is proved using Ohm's law.
