Two wires of copper have lengths \( L \) and \( 2L \) and cross sectional area \( 2A \) and \( A \), respectively. The ratio of their specific resistance would be-
- A \(1:2\)
- B \(1:8\)
- C \(1:1\)
- D \(1:4\)
Answer & Solution
Correct Answer
(C) \(1:1\)
Step-by-step Solution
Detailed explanation
Specific resistance depends only on the material. Both wires are copper. Ratio of specific resistance = \(1:1\)
