In the measurement of a resistance by Wheatstone bridge the known and the unknown resistance are interchanged to neutralize

Question

In the measurement of a resistance by Wheatstone bridge the known and the unknown resistance are interchanged to neutralize (A) end error (B) index error (C) error due to thermoelectric effect (D) random error

In meter bridge experiment, it is assumed that the resistance of the L-shaped plate is negligible but actually it is not so.
The error created due to this is called, end error.
To remove this the resistance box and the unknown resistance must be interchanged and then the mean reading must be taken.

end error

index error

error due to thermoelectric effect

random error
