Examine the data from Part 1. According to the textbook, what should be the relationship between the three voltage readings: V₁, V2, and Vror? How do the data support this? 2. Using the current I and voltage Vror values above and your knowledge of Ohm's law, calculate the equivalent resistance (R) for each of the three series circuits that were tested. Show your work here, and put your answers in the second-to-last column of the table above.
