求戴维等效电路的EPOT基于偏置电阻网络

To model the network shown below in Figure 1 as the Thevenin equivalent shown below in Figure 2, find the Thevenin Voltage (Vth) and the Thevenin Resistance (Rth). In this case, Vth is the same as Vos (with no external load present) and Rth is the resistance looking back from Vos with the voltage sources shorted out. Start by replacing the EPOT with its Thevenin equivalent and then subsTItute that replacement into the original network.
