Arduino Setup and Ohm's Law

Summary

- During the experiment, voltage, amperage, and resistance values were measured and analyzed according to Ohm's Law, considering uncertainties in measurements and resistor tolerances.

Abstract:

• - Explored the influence of propeller geometry and pitch on propeller capability.
• - Compared the performance metrics of four propellers of varying geometries and pitches in a 3x3 wind tunnel.
• - Found performance metrics are dependent on propeller geometry and advance ratio.

Uncertainty and Graph

• - Uncertainty calculations were conducted considering device error and resistor manufacturing tolerance.
• - Uncertainties due to measuring devices do not propagate into other values.

Discussion of Results

• - Voltage drop across the 10kΩ resistor was measured to be 4.980V, slightly outside the expected value.
• - Uncertainties in measurements were attributed to device error and resistor manufacturing tolerances.
• - The measured voltage from the Digital Multi-meter was 4.980V, within the tolerance rate of the 10kΩ resistor.
