? + 。a Vab Fob Two measurements are made on an unknown two-terminal device: 1. When a 2mA current source is connected between nodes a and b with positive current flowing into node b, the voltage is measured to be 48mV with the higher voltage at node a. 2. When a 32 resistor is connected between nodes a and b, the current is measured to be 5mA with current flowing down (from a to b). What are the Thevenin equivalent voltage and resistance of the two-terminal device? Vth= Rth=

Question
**Analysis of an Unknown Two-Terminal Device** **Illustration Description:** The image shows a diagram of an unknown two-terminal device with nodes labeled "a" and "b." The voltage between these nodes is denoted as \( v_{ab} \), with the positive sign at node "a" and negative sign at node "b." **Measurements:** Two key measurements are taken on this device: 1. **Current Source Test:** - A 2 mA current source is connected between nodes "a" and "b." - Current flows positively into node "b." - The voltage measured is 48 mV, with the higher voltage at node "a." 2. **Resistor Test:** - A 3 Ω resistor is connected between nodes "a" and "b." - The current is measured to be 5 mA, flowing from "a" to "b." **Problem Statement:** Determine the Thevenin equivalent voltage and resistance of the two-terminal device. - **Thevenin Equivalent Voltage (\( V_{th} \))**: [Input box] - **Thevenin Equivalent Resistance (\( R_{th} \))**: [Input box]
