Q114 / 120 · VITEEE 2010 · Physics

In Meter bridge or Wheatstone bridge for measurement of resistance, the known and the unknown resistances are interchanged. The error so removed is

Correct answer
A
end correction
B
index error
C
due to temperature effect
D
random error

Solution

To remove the error, resistance box and the unknown resistance must be interchanged and then the mean reading must be taken.

Hence, the correct answer is option: 'A'.
