Resistances in Circuits Equipment Needed: Circuits Experiment Board. Multimeter, Resistors. Purpose: The purpose of this lab is to begin experimenting with resistance, a variable that contributes to the operation of an electrical circuit. Procedure 1. Choose the three resistors having the same value. Enter those sets of colors in Tablel below. We will refer to one as #1, another as #2 and the third as #3. 2. Determine the coded value of your resistors. Enter the value in the column labeled "Coded Resistance" in Table 1. Enter the Tolerance value as indicated by the color of the fourth band under "Tolerance." 3. Use the Multimeter to measure the resistance of each of your three resistors. Enter these values In Table 1. 4. Determine the percentage experimental error of each resistance value and enter it in the appropriate column. Experimental Error = [(! Measured - Coded!)/ Coded] x 100%.

Now connect the three resistors into the SERIES CIRCUIT shown below, using the spring clips on the Circuits Experiment Board to behold the leads of the resistors together without bending them. Measure the resistances of the combinations as indicated on the diagram by connecting the leads of the Multimeter between the points at the ends of the arrows. Series R12 = 10.1 R13= 20.3 R123= 29.9D12--04367C 6. Construct a PARALLEL CIRCUIT, first using combinations of two of the resistors, and then using all three. Measure and record your values for these circuits. Parallel R12 = 5.9 R23 = 5.6 R123 = 3.8 R13 = 10.4 Section Break NOTE: Include also R13 .....Column Break.. Figure 2 Section Break 7. . Connect the COMBINATION CIRCUIT below and measure the various combinations of resistance. Do these follow the rules as you discovered them before? Combination - R -> R. 123 -- R1= 10.5 R23= 5.4 R123= 15.4Figure_3 8. Choose three resistors having different values. Repeat steps 1 through 7 as above, recording your data in the spaces on the next page. Note we have called these resistors A, B and C.
