Questions & Step-by-Step Solutions
In an experiment, the voltage is measured as 12.0 V with an uncertainty of ±0.3 V. What is the absolute error in the voltage measurement?
Step 1: Understand what absolute error means. It is the amount of uncertainty in a measurement.
Step 2: Look at the given voltage measurement, which is 12.0 V.
Step 3: Identify the uncertainty given, which is ±0.3 V.
Step 4: Realize that the absolute error is simply the value of the uncertainty.
Step 5: Conclude that the absolute error in the voltage measurement is ±0.3 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.
