Thevenins theorem states that any linear circuit can be replaced by:

A A current source

B An equivalent voltage source in series with an equivalent resistance

C Just a resistor

D An open circuit

✓ Correct Answer: Option B

Thevenin: V_th = open-circuit voltage, R_th = equivalent resistance (sources zeroed). Simplifies circuit analysis.

💡 Why is B) the correct answer?

The correct answer to the question "Thevenins theorem states that any linear circuit can be replaced by:" is Option B: An equivalent voltage source in series with an equivalent resistance.

The other options — A) A current source, C) Just a resistor, D) An open circuit — are incorrect for this FE Exam Prep question. As explained above: Thevenin: V_th = open-circuit voltage, R_th = equivalent resistance (sources zeroed). Simplifies circuit analysis.
