- A Thévenin 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 figure below. When a 25 k2 resistor is connected to the terminals a,b, the voltage is measured and found to be 105 V. When a 2 k resistor is connected to the terminals a,b, the voltage is measured and found to be 13 V. Find the Thévenin equivalent of the network with respect to the terminals a,b.
