Detailed Solution

Assertion is true but the reason is false.
Assertion:
The statement of Ohm’s law is

V = IR

is correct. This is a fundamental law of physics that states that the voltage

(V)

across an electric circuit is proportional to the current

(I)

flowing through it.
Reason:

V = IR

is the equation which defines resistance is wrong.
According to Ohm's law, the current is inversely proportional to the potential difference, and the resistance is the proportionality constant that is known as the resistance. However, this statement does not specify the material's resistance. Thus, although the proposition is true, the justification is wrong.
