NEET 2024 Physics Resistances in Series and Parallel MCQ Question
A wire of length ‘l’ and resistance 100 Ω is divided into 10 equal parts. The first 5 parts are connected in series while the next 5 parts are connected in parallel. The two combinations are again connected in series. The resistance of this final combination is:
55 Ω
60 Ω
26 Ω
52 Ω
Correct Answer
Detailed Explanation
The resistance of the first 5 parts in series is 50 Ω. The resistance of the next 5 parts in parallel is 10 Ω. The total resistance is 50 Ω + 2 Ω = 52 Ω.
