Q: A voltage measurement is taken as 220 V with an uncertainty of ±5 V. What is the absolute error?
Solution:
The absolute error is given directly as ±5 V.
Steps: 4
Show Steps
Step 1: Understand that the voltage measurement is 220 V.
Step 2: Note that there is an uncertainty associated with this measurement, which is ±5 V.
Step 3: Recognize that the absolute error is the same as the uncertainty in the measurement.
Step 4: Therefore, the absolute error is ±5 V.
