Wheatstone Bridge & Metre Bridge

The resistances in the two gaps of a balanced meter bridge are 'X' Ω\Omega and '3X' Ω\Omega respectively. If the resistances are interchanged the balance point shifts by

Show answer and solution

Answer: (c)

  1. X3X=l100−l⇒l=25\dfrac{X}{3X} = \dfrac{l}{100 - l} \Rightarrow l = 25 cm
  2. After interchange: l′=75l' = 75 cm
  3. Shift =75−25=50= 75 - 25 = 50 cm
  4. So the answer is (c) 5050 cm.
