Answer 2

Hey there!

Thank you for your Question!

Ohm's Law:

According to Ohm's law, under constant physical conditions of temperature and pressure, the current flowing through the conductor is directly proportional to the Voltage or potential difference across the ends of the terminals.

i.e $\bold{\boxed{V\propto I}}$

or, $\boxed{\frac{V}{I} = constant = R}$

Equation for Ohm's Law:

$\boxed{\textbf{V = I R}}\\\textbf{where,}\\V = \textbf{Potential difference}\\I = \textbf{Current}\\R=\textbf{Resistance}$

Good Studies!
