NEET Physics Resistance & Resistivity MCQ Question
What is the relationship between voltage (V) and current (I) in a material that obeys Ohm's law?
V is directly proportional to I.
V is inversely proportional to I.
V is independent of I.
V equals the square of I.
Correct Answer
Detailed Explanation
According to Ohm's law, the voltage across a conductor is directly proportional to the current flowing through it, which is expressed as V = IR.
