The various resistance of a wheatstone bridge are shown in figure. The battery has an internal emf of 8 V with negligible internal resistance. If the sensitivity of the galvanometer is 12 mm/µA with an internal resistance of 150 Ω.
What will be the sensitivity of the bridge in terms of deflection per unit change in resistance.
  • a)
    14.8 mm/Ω
  • b)
    12.3 mm/Ω
  • c)
    16.4 mm/Ω
  • d)
    15.6 mm/Ω
Correct answer is option 'A'. Can you explain this answer?

Resistance of unknown resistor required for balance,
Therefore, the deviation in unknown resistance from the balance condition,
ΔR = 1650 - 1600
= 50Ω
So now Thevenin source emf,
ε0 = 0.039V Now the internal resistance of bridge looking into terminal C & d−
= 481.95Ω
Hence the current through the galvanometer
then deflection of galvanometer
θ = Si. Ig
= 12 × 61.7mm
θ =740.4mm
Therefore, sensitivity of bridge
