A data acquisition system is to be used to measure the value of a maximum 120-V line voltage. The maximum input voltage to the data acquisition system is 8 V and its input impedance is 1 M?. The output impedance of the power line circuit is 0.5 ?.
(8) Determine the value for resistor R2 in Figure 3.15 if R1 has a value of 100 k ? '.
(b) Determine the power dissipated by the two resistors.
(c) Determine the loading error of the line voltage at the attenuator input.
