23. Determine theoretical value for the equivalent resistance. Use the actual values R₁ and R₂ that you calculated in Part 1 with Equation 2 to calculate the equivalent resistance REQ 1,2 for resistors R₁ and R₂ in parallel. Record the value. Then use the equivalent resistance REQ 1,2 and the actual value R3 that you calculated in Part 1 with Equation 1 to calculate the equivalent resistance REQ = REQ 1,2 + R3 of an arrangement of the three resistors, where R3 is in series with the parallel combination of R₁ and R₂. REQ = R₁ + R₂ + Equation 1 + RN 1/REQ = 1/R₁+1/R₂ + 1/R3 + Equation 2 ... + 1/RN
1. In Parts 2, 3, and 4 you were asked to calculate the percentage errors in your experimental values Rexp compared the theoretical values REQ. Were the percentage errors within the range you would expect? What do your results you to conclude about the equations used to calculate the equivalent resistances for resistors arranged in series a in parallel? If your percentage errors tend to be high, what could be some reasons? 2. Two resistors, a 50 and a 20 Q, can have more than one equivalent resistance. How is this possible?
3. Describe three ways three identical resistors can be arranged in a circuit to yield three different equivalent resistances. 4. Two resistors A and B are arranged in series in one branch of a parallel arrangement. The other branch contains a single resistor, C. This parallel arrangement is in series with a single resistor D. Describe how you would find the equivalent resistance of the group.
