Propagation Addition
Mediumphysics
When adding two measured quantities (with absolute errors ΔA, ΔB), resultant absolute error is:
Select the correct option:
Solution
Incorrect! Answer:
ΔA + ΔB
In addition or subtraction, the absolute errors always add up for the maximum possible error.
- If Z=A+B or Z=A−B
- The maximum absolute error in Z is ΔZ=ΔA+ΔB. This reflects the worst-case scenario where errors in both measurements contribute in the same direction.
