You have gone into the lab to find that someone has done current and voltage measurements for these resistor combinations already. The voltage across just resistor R1 is found in column V₁; the voltage across just resistor R₂ is in column V2, and the voltage across the series combination of resistors is in column Vror. The current through the ammeter is in column. I.

5. For each of these three series circuits, calculate the percent error between your experimental result from Ohm's Law and the predicted equivalent resistance value for series resistors. Do these values seem reasonable, given that resistors are labeled with percent tolerance ratings that allow for their real resistance values to differ from their labeled values? 2
