In the given circuit, what will be the equivalent resistance between the points A and B ?

Options

  1. A10 / 3
  2. B20 / 3
  3. C10 / 5
  4. D5

Correct answer

A. 10 / 3

Step-by-step solution

2 3 = 4 6 Given, circuit is a balanced Wheatstone's Bridge. So, 10 resistance will be ineffective. Equivalent resistance of upper arms R₁=2+3=5 Equivalent resistance of lower arms aligned R₂ & =4+6=10 R_ A B & = R₁ R₂ R₁+R₂ & = 5 10 5+10 & = 50 10 = 10 3 aligned
