3. The box shown below contains a circuit with two terminals ($A, B$) to connect to the outside world. The open circuit voltage measured across the two terminals is $V_{OC} = 5V$. The short circuit current measured by shorting the terminals through an ammeter is $I_{SC} = 2A$. $V_{oc} = 5V$ $I_{SC} = 2A$ 3.1 (5pts) Calculate the Thevenin equivalent circuit, $V_{Th}$ and Thevenin equivalent resistance, $R_{eq}$ and label your circuit with these values. 3.2 (5pts) Determine the power consumed by a $7.5\Omega$ resistor connected to the thermals ($A,B$).
