Part II: Parallel circuits Reg V(Ohm Law) paralei (a) cators) 47 0101 228 12 22 47 PART 2 ANALYSIS Examine the results of Part II. What is the relationship between the three voltage readings: Vi, V2, and VTOT? 1. 2. Using the measurements you have made above and your knowledge of Ohm's law te the equivalent resistance (R) of the circuit for each of the three parallel circuits you tested 3. Study the equivalent resistance readings for the parallel circuits. Devise a rule for the equivalent resistance (Ra) of a parallel circuit with two resistors? Look it up if necessary - or to check. The rule: Use the rule to calculate equivalent resistance (Req) of two resistors connected in parallel from the factory values of the resistors. Note these values in the last column of the data table. 4. 5. For each of the three parallel circuits, compare the experimental results with the resistance calculated using your rule. In evaluating your results, consider the tolerance of each resistor by using the minimum and maximum values in your calculations Examine the results of Part II. What do you notice about the relationship between the three voltage readings Vi, , and Vror in parallel circuits. 6.
