Challenge Problems
Push your limits with challenges.
Question 1
In an experiment, the current is measured as 0.1Β±0.002 A and the resistance is found to be 150Β±3 Ξ©. Calculate the voltage and uncertainty in the voltage.
π‘ Hint: Make sure to calculate each part of the formula separately.
Question 2
If you know the resistive losses in your circuit components lead to the following: 220Ξ© at a tolerance of Β±0.5Ξ© and current flow is at 2.5Β±0.01A. Determine the uncertainty in voltage and the actual voltage.
π‘ Hint: Convert everything to decimals carefully and use the right propagation formula.
