$\large\underline{ \underline{ \green{ \bold{ohm's\:Law}}}}$

In 1827 , a German physicist Georg Simon Ohm found the relationship between the current flowing in a metallic wire and potential difference across it's terminals .

The potential difference across the ends of a given wire circuit is directly proportional to the current flowing through it. provides it's temperature remains same . This is called ohm's law.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀v ∝ I

⠀⠀⠀⠀⠀⠀⠀$\bf\:\frac{V}{I}=constant$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀=R

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ${ \boxed{ \pink {\bf{ V \: =\:IR\:}}}}$
