Given:
Solution:
In the series combination, the resistance are added.
Here, the error is added because is in addition.
In parallel combination, the reciprocal of the resistances are added.
After we differentiate the parallel combination formula we get,
We need to keep the error on one side and bring the rest on another side.
On rounding, we get,
