Part II. Parallel Set up a parallel circuit with two arbitrary resistances R₁ and R₂ as in Fig. 6. Power Supply R1 R2 Figure 6: Parallel circuit The parallel circuit will be repeated three times: Instructor data (to see what the data would look like for a real circuit with all the possible errors involved). ● Group data- simulation (you may collect one set of data as a group as you work together in class). ● Individual data-simulation (the last data set must be yours alone). Power Supply R2 Figure 7: Connecting an ammeter for each resistor and the total resistance. Connecting the voltmeter. Measure the voltage drop V₁, V2, and VT across the parallel resistors. Measure the currents 1₁ and 12 through each resistor and the total current IT through the parallel combination. Take a screenshot photo once all your meters are attached and include it in your notes. From each measured voltage and current, find R₁, R2, and Rp(exp). From VT and IT directly, find the experimental effective resistance Rp(exp) from Ohm's Law. Compare this with the prediction Rp(theo) (Eq.(5)) using the above R₁ and R₂ values and discuss your results. Question 5. Do you confirm the parallel resistance formula, Eq. (5)? Ow R1

Part III. Series-Parallel Set up the circuit of Fig. 8. Choose three arbitrary resistors R₁, R₂, and R3. Draw where you would place ammeters and voltmeters. This is a drawing so include as many as is needed to measure everything despite not having multiple voltmeters available in the simulation or in lab. By measuring currents and voltage drops as in Parts I and II above determine R₁, R₂, R3. Determine the overall voltage drop VT across and total current IT through the series-parallel combination. From VT and IT directly, find the experimental effective resistance Re(exp) and its uncertainty. Compare with the theoretical prediction Re (theo) of Eq. (7) using the above R₁, R2, R3 values and discuss your results. Power Supply R1 R2 R3 Figure 8: Series-Parallel circuit. Question 6. Do you confirm the series-parallel resistance formula, Eq. (7)? Question 7. Write an equation for the relationship between the voltages in a series circuit, between the currents in a series circuit, between the voltages in a parallel circuit, and between the currents in a parallel circuit based on your data. (You will have 4 equations.) Does this agree with Kirchoff's Laws?
