MCQ
Which error is removed when the known and unknown resistances are interchanged in a Meter Bridge?
- APercentage error
- BMeasurement error
- ✓End error
- DIndex 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.
