Day 14:

Activity #1

For this activity, we measured the current,  I, and voltage, V at several points in a parallel configuration as well as a series configuration. 

Activity #2 Decoding color for resistor

In order to practice recognizing the values or various resistors, we collected 4 band code resistors and 5 band code resistors and used the code legend to determine the rating of the each resistor.

.

Then we compared this calculated value to the measurements we took with an R-reader
For the 4 band code resistor we had about 99% accuracy. For the 5 band code resistor, we had slightly less with 97%.

Activity #3: Equivalent Resistances For Networks

We set up various resistors with known resistances in a combination of series and parallel configurations according to diagram that we were show. We calculated the value of its equivalent resistance and then we compared that value to the measurement taken by the R-Reader.

We were off by about 2%, which we considered a success.
