Question
Ohm's law is applicable when temperature of the conductor is constant Statement B: Ohms law states that the voltage applied is inversely proportional to current
Solution
Statement A: This is correct. Ohm's law, which states that the current through a conductor between two points is directly proportional to the voltage across the two points, is applicable when the temperature of the conductor is constant. This is because changes in temperature can affect the resistance of the conductor, which would in turn affect the current.
Statement B: This is incorrect. Ohm's law actually states that the voltage applied across a conductor is directly proportional to the current flowing through it, not inversely proportional. The formula for Ohm's law is V = IR, where V is voltage, I is current, and R is resistance. This means that if you increase the voltage, the current will also increase, assuming the resistance stays the same.
