Resistor networks are sometimes used as volume-control circuits.
In this application, they are referred to as resistance
attenuators or pads. A typical fixed-attenuator pad
is shown in the figure. In designing an attenuation pad, the
circuit designer will select the values of R1 and R2 so that the
ratio of vo/vi and the resistance seen by the input voltage source
Rabboth have a specified value. (Figure 1)

The material constant B is to be determined for a particular
thermistor using the circuit below. The thermistor has a resistance
of 60 k at 25C. The reference resistor in the circuit, R1, has a
resistance of 130.5 k 2. The dissipation constant is 0.09mW/C. The
voltage source used for the measurement is constant at 1.564 V. The
thermistor is to be used at emperatures ranging from 100 to 150C.
