NEET 2021 Physics Resistors in Series and Parallel MCQ Question
The effective resistance of a parallel connection that consists of four wires of equal length, equal area of cross-section and same material is 0.25 Ω. What will be the effective resistance if they are connected in series ?
0.25 Ω
0.5 Ω
1 Ω
4 Ω
Correct Answer
Detailed Explanation
In parallel, the resistance is 0.25 Ω, so each wire has a resistance of 1 Ω. In series, the total resistance is the sum, which is 4 Ω.
