NEET Physics Ohm's Law MCQ Question
A resistor has a resistance of 20 ohms. What is the current flowing through it when a voltage of 10 volts is applied across it?
0.5 A
2 A
5 A
10 A
Correct Answer
Detailed Explanation
Using Ohm's Law (V = IR), the current I can be calculated as I = V/R = 10V/20Ω = 0.5 A. This demonstrates the linear relationship between voltage and current in resistors that obey Ohm's Law.
