In this circuit, you have several resistors in a series parallel combination. Though you can calculate the effective
resistance of the circuit, you would find it tedious, especially when you have to consider the tolerance values of each
resistor. Instead, use the DMM to measure the total resistance of the circuit as show in Figure 2.2.
Figure 2.2. DMM Resistance Measurement With 5 Percent Tolerances
Using the DMM, you can easily view the actual resistance of your circuit quickly without having to conduct several
calculations and tolerance estimations. The total resistance according to Figure 2.2 is 176.855 Ω.
Once you have taken your resistance measurement, you can take your voltage measurement. When taking voltage
measurements with a DMM, consider whether your source is AC (alternating current) or DC (direct current) and set your
DMM to the correct mode. For this chapter, use an FGEN as your voltage supply and take the measurement using your
DMM as shown in figures 2.3a and 2.3b.
