QNEET-2024-Ph-152: NEET 2024 Physics - Class 12 NEET-2024-Ph-152 Solution: A uniform metal wire of length l has \(10 \) resistance. Now…

A uniform metal wire of length l has 10Ω10\Omega resistance. Now this wire is stretched to a length 2l and then bent to form a perfect circle. The equivalent resistance across any arbitrary diameter of that circle is 10Ω10\Omega 5Ω5\Omega 40Ω40\Omega 20Ω20\Omega

Multiple Choice Options

  • A 10Ω10 \Omega 10�
  • B 5Ω5 \Omega 5�
  • C 40Ω40 \Omega 40�
  • D 20Ω20 \Omega 20�

Step-by-Step Verified Solution

R 0 = 10 � After stretching its length upto 2 l R 1 = n 2 R 0 = 4 R 0 = 40 � R A B = 20 _ 20 20 + 20 = 10 �
