प्रश्न
- Name and state the law which relates the potential difference and current in a conductor.
- What is the necessary condition for a conductor to obey the law named above in part (a) ?

उत्तर
- The law is called Ohm's law. It states that the current flowing through the conductor is directly proportional to the potential difference across the ends of the conductor, given that the temperature remains constant.
- The temperature should remain constant.
