Which one of the following combinations of open circuit voltage and the Thevenin's equivalent resistance represents the Thevenin's equivalent of the circuit shown in the given figure? [Figure description: A 1 V source on the left in series with a 1 kΩ resistor (current I1 flowing right) along the top wire. A dependent current source 99 I1 (arrow up) is connected in parallel between top and bottom wires at the right, ahead of terminals a (top) and b (bottom).]
- A. 1 V, 10 Ω
- B. 1 V, 1 kΩ
- C. 1 mV, 1 kΩ
- D. 1 mV, 10 Ω
Answer: A. 1 V, 10 Ω
Explanation: Open-circuit voltage Voc = 1 V since I1 = 0. For Thevenin resistance, applying a test voltage or KCL gives Rth = 10 Ω.
