Question
**Educational Content: Finding Thevenin Equivalent** **Problem Statement:** Determine the value of components in the Thevenin Equivalent for the following circuit at terminals a and b. **Circuit Description:** - A circuit with a 100 V voltage source connected in series with a 10 Ω resistor. - A node connects the series combination to two branches: 1. A parallel branch with a 20 Ω resistor and a 5 A current source pointing to the right. 2. Another parallel branch with a 30 Ω resistor, which connects directly to terminals a and b. - Below terminal b, a branch contains a 4 A current source pointing upwards in series with a 40 Ω resistor. **Task:** Develop the Thevenin equivalent circuit by calculating: 1. The Thevenin voltage (\(V_{th}\)) across terminals a and b. 2. The Thevenin resistance (\(R_{th}\)) seen from terminals a and b with independent sources turned off (replace voltage sources with short circuits and current sources with open circuits). **Approach:** - Calculate \(V_{th}\) by finding the open-circuit voltage across terminals a and b. - Calculate \(R_{th}\) by deactivating all independent sources and finding the equivalent resistance across terminals a and b.
