### Transcription The circuit shown in Figure 1b is the Thevenin equivalent circuit of the circuit shown in Figure 1a. Find the value of the open-circuit voltage, \( V_{OC} \), and Thevenin resistance, \( R_{th} \). Also, determine the value of the short circuit current, \( I_{SC} \). #### Diagram Explanation (Figure 1a) - **Voltage Source**: There is a 10 V voltage source. - **Resistors**: - A 3 Ω resistor is connected in series with the voltage source. - A 5 Ω resistor is connected in series with a dependent voltage source in the upper branch of the circuit. - A 6 Ω resistor is connected in parallel to the dependent source in the vertical branch. - **Dependent Voltage Source**: A dependent voltage source represented as \( 2i_a \) is placed in series with the resistors. The controlling current \( i_a \) flows through the 6 Ω resistor in the vertical branch, showing that the dependent source depends on \( i_a \). - **Current Direction**: The current \( i_a \) is shown moving downward through the 6 Ω resistor. The complete circuit needs analysis to find the open-circuit voltage \( V_{OC} \), Thevenin resistance \( R_{th} \), and the short-circuit current \( I_{SC} \).

**Figure 1b: Thevenin Equivalent Circuit Diagram** This image illustrates a Thevenin equivalent circuit, a simplified representation of a more complex electrical circuit. The diagram consists of the following components: - **V_oc (Open-circuit Voltage):** Indicated by a voltage source symbol, representing the voltage measured across the terminals when no load is connected. - **R_th (Thevenin Resistance):** Shown as a resistor in series with the voltage source, this represents the equivalent resistance seen at the terminals when all independent voltage sources are replaced by short circuits and all independent current sources are replaced by open circuits. - **Ground Symbol:** Displayed at the bottom right, indicating the common reference point in the circuit. The circuit is used to simplify the analysis of power systems and networks by transforming complex circuits into a single voltage source and series resistance.
