Question

Define Ohm's law?

Give the exact definition. Who gave this law? ​

Answer 1

$\color{red}\huge\bold\star\underline\mathcal{Namaste}\star$

Ohm's law is a law that states that the voltage across a resistor is directly proportional to the current flowing through the resistance. Ohm's law is named for German physicist Georg Ohm .

Answer 2

$\huge{ \underline{ \mathfrak{Ohm's \: Law}}}$

Ohm's law gives a relationship between current flowing through a metallic wire and the potential difference across it's terminals.

This law states that the current flowing through a conductor is directly proportional to the potential difference applied across the two ends, keeping the physical changes like the temperature unchanged.

Let's take the potential difference as V.

And let's take the current as I.

Now according to Ohm's Law,

• V = IR

This can also be written as

$I \: = \frac{V}{R}$

Where,

I = current

V = Potential Difference

R = Resistance

Resistance here is the constant of proportionality.
