Problem 4.71 Part A A Thevenin equivalent can also be determined from measurements made at the pair of terminals of interest. Assume the following measurements were made at the terminals a,b in the circuit in the figure. When a 2012 resistor is connected to the terminals a,b, the voltage Wab is measured and found to be 120 V When a 502 resistor is connected to the terminals a,b, the voltage is measured and found to be 159 V. (Figure 1)...
