Question

Ohm’s law is valid when ______.

Options

• temperature increases

• temperature decreases

• temperature remains constant

• graph between I and V is a curve

Answer 1

Ohm’s law is valid when temperature remains constant.

Explanation:

According to Ohm’s law, the current flowing through a conductor is directly proportional to the potential difference across its ends, provided its temperature and other physical conditions remain constant. This is because the resistance of a conductor changes with temperature.
