Using a voltmeter, 2. Measure the resistance value of all resistors. adjust the power supply level to 10 V dc. Record the value of each resistor in Table 1. Fill in all empty cells in the column below 11. Measure the voltage drops across each the resistor number resistor as indicated in Figure 2. For example, the voltmeter is shown connected 3. Connect the series arrangement 1 shown in across R1 to measure VR1. Record the results in Table 3. Figure 1 by connecting resistors R1 and R4 in series. 12. After recording the measured voltage drops, 4. Using the measured values of the individual compare the measured and calculated values. Use the following formula for resistors in the circuit, compute RT. Record this value in Table 1. To measure total determining this percentage: resistance, it is necessary to measure across the entire circuit – from point A to point B. difference between meas. and calc. values %  X100 5. Remove one of the resistors (do not calc. values</p><p> reconnect the circuit) while measuring RT, 13. If any error is greater than 10%, ask your and record the results of your measurement instructor for further directions. in Table 1. 14. Measure the current at points A, B, C, and D 6. Complete steps 3 – 5 for resistor in Figure 2. Record this information in combinations 2 and 3 in Figure 1. Table 4.</p><p>Section 2: Series Voltage and Current.
