The Thevenin equivalent voltage at terminals a-b is _________________.
10 V
The Thevenin equivalent voltage (Vth) at terminals a-b is the open-circuit voltage when no load is connected.
Procedure:
- Open terminals a-b (remove any load).
- Apply KVL/KCL or superposition to find voltage across a-b.
- Vth = Voc at terminals a-b.
The circuit with specific values is in the original question paper. The correct answer corresponds to Option 2.
