NEET 2021 Physics Resistors in Series and Parallel MCQ Question

Type: MCQ-conceptual-Easy-Class 12

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 ?

A

0.25 Ω

B

0.5 Ω

C

1 Ω

D

4 Ω

Correct Answer

Option D

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.
