In the given circuit, current I is independent of the resistance R₆ . Then

Options

  1. AR₁ R₂ R₅=R₃ R₄ R₆
  2. B1 R₅ + 1 R₆ = 1 R₁+R₂ + 1 R₃+R₄
  3. CR₁ R₄=R₂ R₃
  4. DR₁ R₃=R₂ R₄

Correct answer

C. R₁ R₄=R₂ R₃

Step-by-step solution

If resistance R₁, R₂, R₃, R₄ and R₆ from Wheatstone bridge, then current will independent of resistance R₆ . For this, R₁ R₂ = R₃ R₄ R₁ R₄=R₂ R₃
