NEET Physics Ohm's Law MCQ Question
Consider a circuit where a resistor with resistance R is connected in series with a battery of voltage V. A voltmeter is connected across the resistor. Which of the following describes the correct relationship between the current I through the resistor and the voltage V across it according to Ohm's Law?
I is directly proportional to V, assuming R is constant.
I is inversely proportional to V, assuming R is constant.
I is independent of V, assuming R is constant.
I is directly proportional to R, assuming V is constant.
Correct Answer
Detailed Explanation
According to Ohm's Law, current I through a resistor is directly proportional to the voltage V across it when the resistance R is constant, which is represented by the equation V = IR.
