1. Become familiar with the power supply, the analog and digital meters, and the resistor color code. B. Use of the Ohmmeter. 3. Use three resistors rated (according to their code) 47 ohm, 4.7 k-ohm, and 680 k-ohm. 4. Measure the resistance of the resistors using the ohmmeter. C. Measurement of Resistance Using an Analog Ammeter and a Voltmeter. 5. Use the resistor rated 47 ohm in the arrangement shown in Figure 1a. Set the voltage of the supply to 6 V. Measure the voltage and the current indicated in the figure. 6. Repeat procedure 5 using the arrangement of Figure 1.1b. Tabulate the measurements. Vs V A I www R Vs (b) (a) Figure 1.1.
