MCQ
Which error is removed when the known and unknown resistances are interchanged in a Meter Bridge?
  • A
    Percentage error
  • B
    Measurement error
  • ✓
    End error
  • D
    Index error
✓

Answer

Correct option: C.
End error

End error is removed when the known and unknown resistances are interchanged in a Meter Bridge. This additional length has a resistance known as end resistance. So, when an end error arises, it can be removed by interchanging the known and unknown resistances and taking the mean of the resistances determined.
