Questions & Step-by-Step Solutions
In an experiment, the voltage is measured as 12.0 V with an uncertainty of ±0.5 V. What is the absolute error in the voltage measurement?
Step 1: Understand what voltage is being measured. In this case, it is 12.0 V.
Step 2: Identify the uncertainty in the measurement. Here, the uncertainty is ±0.5 V.
Step 3: Recognize that the absolute error is the same as the uncertainty in the measurement.
Step 4: Conclude that the absolute error in the voltage measurement is ±0.5 V.
Absolute Error – The absolute error is the uncertainty associated with a measurement, indicating the range within which the true value is expected to lie.
