Questions & Step-by-Step Solutions

A voltage is measured as 12.0 V with an uncertainty of ±0.1 V. What is the absolute error?
  • Step 1: Understand what voltage is. In this case, the voltage is measured as 12.0 V.
  • Step 2: Identify the uncertainty given in the measurement. Here, the uncertainty is ±0.1 V.
  • Step 3: Know that absolute error is defined as the uncertainty in the measurement.
  • Step 4: Conclude that the absolute error for this measurement is the same as the uncertainty, which is ±0.1 V.
  • Absolute Error – The absolute error is the amount of uncertainty in a measurement, which is the same as the uncertainty value.
  • Measurement Uncertainty – Understanding how uncertainty is represented and its significance in measurements.
