Question: In an experiment, the measured value of a voltage is 12.0 V with an uncertainty of ±0.2 V. What is the maximum possible error?

Options:

  1. 0.2 V
  2. 0.1 V
  3. 0.5 V
  4. 0.0 V

Correct Answer: 0.2 V

Solution: 

Maximum possible error is equal to the uncertainty, which is ±0.2 V.

Questions & Step-by-Step Solutions

In an experiment, the measured value of a voltage is 12.0 V with an uncertainty of ±0.2 V. What is the maximum possible error?
  • Step 1: Identify the measured value of the voltage, which is 12.0 V.
  • Step 2: Identify the uncertainty given, which is ±0.2 V.
  • Step 3: Understand that the maximum possible error is the same as the uncertainty.
  • Step 4: Conclude that the maximum possible error is ±0.2 V.
  • Measurement Uncertainty – Understanding how to interpret and apply uncertainty in measured values.
  • Maximum Possible Error – Recognizing that the maximum possible error in a measurement is defined by its uncertainty.
