- APercentage error
- BMeasurement error
- CEnd error
- DIndex error
Explanation:
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.
