CBSE Class 10 Science 2019 · Paper 31/5/1 · Question 1
State Ohm’s law.
Answer
At constant temperature, the potential difference across a metallic conductor is directly proportional to the current through it: .
Ohm’s law: the potential difference across the ends of a metallic conductor is directly proportional to the current flowing through it, provided its temperature and other physical conditions remain the same. That is, , or , where is the resistance of the conductor.
