One afternoon, Justine suddenly remembers that he has a term paper due Tuesday morning. When he sits at his computer to start typing, he discovers that the computer mouse doesn 't work. After disassembly and some inspection, he finds that the mouse conta- ins a printed circuit board that is powered by a 5-V supply contained inside the computer case. Furthermore, the board is found to contain several resistors, some op-amps, and one unidentifiable device, which is connected directly to the computer's 5-V supply as shown in the figure below Using a voltmeter to measure the node voltages, Justine confirms that all resis- tors and op-amps are functioning properly and the power supply voltage reaches the mouse board. However, without knowing the mystery device's function within the circuit, he cannot determine its condition. A phone call to the manufacturer reveals that the device is indeed linear but is also proprietary. With some persuasion, the manufacturer's representative agrees that if Justine can find the Thevenin equivalent circuit for the element at nodes A-B with the computer on, he will tell her if it is functioning properly. With a single 1-ko resistor and a voltmeter available on hand, Justine attacks the problem. To find the Thevenin equivalent for the unknown device, together with the 5-V source, Justine first isolates nodes A and B from the rest of the devices on the board to measure the open-circuit voltage. The resulting voltmeter reading is VAB = 2.4 V. Then she connects the 1-kQ resistor at nodes A-B. The voltmeter reading is now VAB = 0.8 V. a) What is the equivalent Thevenin's voltage ? V (do not write units) b) What is the equivalent Thevenin's resistance ? kQ (round off, no decimal point, no units) Unknown OA element V = 5V
