NEET Physics Kirchhoff's Laws MCQ Question
In a closed loop containing resistors and batteries, the algebraic sum of potential differences is zero. If the loop consists of two resistors of 10Ω and 15Ω and a battery of 5V, what is the current in the loop if the total resistance is 25Ω?
0.2 A
0.5 A
1 A
2 A
Correct Answer
Detailed Explanation
Using Kirchhoff's Loop Rule, the sum of potential differences around the loop is zero. Thus, 5V = I * (10Ω + 15Ω). Solving gives I = 0.5 A.
