NEET Physics Resistance & Resistivity MCQ Question
When connecting two cells in series, what is the equivalent internal resistance if each cell has an internal resistance of 0.5 ohms?
1.0 ohm
0.25 ohms
2.0 ohms
0.5 ohms
Correct Answer
Detailed Explanation
The equivalent internal resistance of cells in series is the sum of their individual internal resistances, as per equation r_eq = r_1 + r_2 from the NCERT context.
