Question

what is ohms law and it expression

Answer 1

According to home floor voltage is directly proportional to current.

v directly proportional to I.
V=IR
I=V/R ( R is the Ohm 's constant.)

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!
