The value of the gain of the voltage divider is determined by the resistances, R1 and R2, of the two resistors that comprise the voltage divider as shown in Figure 2-1. If you select 1 Ohm for R1 and 2 Ohms for R2, then the output current will be 5 mA. The constant of proportionality is called the gain of the voltage divider. These battery, A Photocell is a transducer used to detect and measure light and other radiations. source voltage divided by the equivalent resistance of the string. 1 2 . 0000004574 00000 n >> 1 0 obj 0000010877 00000 n 5.
