**Determining Thevenin’s Equivalent for Maximum Power Transfer** For the circuit depicted, we aim to calculate: - The Thevenin’s Equivalent Voltage \( V_{th} \) - The Thevenin’s Equivalent Resistance across \( R \) Additionally, we need to establish the optimal \( R \) value for maximum power transfer. **Circuit Description:** The circuit consists of: - A voltage source \( E_1 = 18 \, V \) - A resistor \( R_1 = 3 \, \Omega \) - A second resistor \( R_2 = 8 \, \Omega \) - A second voltage source \( E_2 = 12 \, V \) - Resistor \( R \) connected in between the junctions of \( R_1 \) and \( R_2 \) The circuit forms a loop with \( E_1 \), \( R_1 \), \( R \), \( R_2 \), and \( E_2 \). **Objectives:** 1. Calculate \( V_{th} \) by determining the open-circuit voltage across \( R \). 2. Determine the Thevenin resistance by deactivating the voltage sources and calculating the equivalent resistance across \( R \). 3. Find the value of \( R \) for which maximum power is transferred, equating \( R \) to Thevenin’s equivalent resistance. This analysis is pivotal in optimizing the load for maximum efficiency in power transfer scenarios.
