Questions & Step-by-Step Solutions

A voltage measurement is taken as 220 V with an uncertainty of ±5 V. What is the absolute error?
  • 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.
  • Voltage Measurement – Understanding how voltage is measured and the significance of uncertainty in measurements.
  • Absolute Error – The absolute error is the amount of uncertainty in a measurement, represented as the range of possible values.
