Parallel & Series Circuits The resistance of three resistors was veried in the previous lab. What happens when they connected up together? If they are connected 3 in a row, in series, it's simple -just add them up. If 3 resistors of 10, 20, and 30 Ohms respectively, in series they would have a total equivalent resistance of 60 Ohms. If they are connected in parallel, they must be added together differently, as seen in the following equation: 1 1 1 1 ++ = R1 R2 R3 Req In a parallel circuit, those same three resistors would have an equivalent resistance ofabout 5.5 Ohms. For this experiment, create two circuits one parallel and one series. Use the equations to calculate the equivalent resistance for each circuit and verify this with the multimeter. The instructor may want pictures of the circuits and multimeter. 1. In the image above, what is the total resistance of the circuit? 2. What is the total resistance of a circuit when R1 (7-kiloOhm) is in series with a parallel combination of R2 (20-kiloOhm}, R3 (36-kiloOhm}, and R4 (45-kiloOhm)? 3. If a seriesparallel circuit has all 30-Ohm resistors, what is the total resistance when R1 is in series with a parallel circuit consisting of R2 and R3? Content and Analysis 1.
