state and explain Ohm's law

Answer 1

hey dear


here is your answer

About Ohm's law

_______________


In 1827 A German physicist George Simon Home they found Ohms law

____________________________


The potential difference V accross the ends of a given metallic wire in an electric current is directly proportional to the current flowing through it provided it's temperature remains the same


This is Called Ohm's Law

____________________________


Some factors

___________



R is constant at given metallic wire at a given temperature and is called it's resistance .

It is the property of a conductor to resist the flow of charges through it .


it's SI unit is ohm represented by the Greek letter

R = V / I



_________________________________&



If the potential difference across the two ends of a conductor is 1 V and the current through it is 1 A then the resistance R of the conductor


1 Ohm = 1 Volt
_______
1 ampere


as we can write [ I. = V / R ]

________________________________


It states that


√ Resistance is inversely proportional to its resistance


√ if resistance is doubled the current get halved

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!
