NEET Physics Electromotive Force and Internal Resistance MCQ Question
A storage battery of emf 8.0 V and internal resistance 0.5 Ω is being charged by a 120 V dc supply using a series resistor of 15.5 Ω. What is the terminal voltage of the battery during charging?
11.5
5
12.0
5
Correct Answer
Detailed Explanation
The terminal voltage during charging is calculated by considering the voltage drop across the internal resistance and the external resistor. Ω's law and Kirchhoff's loop rule are applied.
