In a Wheatstone's bridge, the resistances in four arms are as shown in the figure. The balancing condition of the bridge is

Options

  1. AP Q = R S ₁+ S ₂
  2. BP Q = R ( S _ i S ₂ ) S ₁+ S ₂
  3. CP Q = R ( S ₁+ S ₂ ) 2 ~S ₁ ~S ₂
  4. DP Q = R ( S ₁+ S ₂ ) S ₁ ~S ₂

Correct answer

D. P Q = R ( S ₁+ S ₂ ) S ₁ ~S ₂

Step-by-step solution

For balancing the bridge, aligned & P Q = R S & ~S = S ₁ ~S ₂ ~S ₁+ S ₂ . ( S ₁, ~S ₂ are in parallel ) & P Q = R ( ~S ₁+ S ₂ ) S ₁ ~S ₂ aligned
