Voltage Dividers
... To illustrate how a series string of resistors acts as a voltage divider, we will examine Figure 16, where there are two resistors in series. As you already know, there are two voltage drops: one across R1 and one across R2. We call these voltage drops V1 and V2, respectively, as indicated in the di ...
