10. Outputs: Noah, Andrew, Tyler, Cooper

The objective of the week was to measure the current consumption of an output

For the output, I used a simple LED with a current limiting resistor. This would allow for a easy setup, as well as I can use ohms law to check that the current consumption is where its expected.

In the test, the multimeter reported a current consumption of around 15 ma. Additionally, the power supply also monitors current, but it reported a current consumption of 10 ma

Actually calculating the current using the equation I=V/R, it should be using, based off a resistance of 220 ohms in the resistor and a voltage of exactly 5v, 22 ma. This is 40% higher than the actual usage, which hints that there is resistance in the wires or power supply.
