Chapter 3, Problem 3.58P

You need to determine the Thévenin equivalent circuit of a more complex linear circuit. A technician tells you she made two measurements using her DMM. The first was with a $10\text{-kΩ}$ load and the load current was $91\text{μA}\text{.}$ The second was with a $1\text{-kΩ}$ load and the load voltage was 124 mV. Calculate the Thévenin equivalent circuit as shown in Figure P3-58.
