Question

what is Ohm's law ? Explain

Answer 1

Ohm's law state that potential difference applied in a conductor (V) is directly proportional to the Current(I) flowing in the conductor provided that temperature remains constant.
mathematically, it can be written ...
V directly proportional to I
V = IR ( where R is constant of proportionality and called as Resistance).

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!
