Question
A student obtained following observations in an experiment of meter bridge to find unknown resistance of given wire :
The most accurate value of unknown resistance will be
The most accurate value of unknown resistance will be
Options
A.2.65 Ω
B.2.77 Ω
C.2.89 Ω
D.2.25 Ω
Solution
As bridge is maximum sensitive because all four resistances are nearly same. but for maximum sensitivity l should be close to 50
