Thevenin equivalent circuit problem

Click For Summary
SUMMARY

The discussion focuses on calculating the Thevenin equivalent circuit, specifically determining the Thevenin resistance (RTh). The participants confirm that the combined resistance of R2 and R4 in parallel with R1 yields a value of 6 Ω. They further establish that the total Thevenin resistance, RTh, which includes R3 and the previously calculated equivalent resistance, results in a final value of 8 Ω. The conclusion emphasizes that the Thevenin resistance cannot be less than R3.

I start with the Thevenin equivalent.

[tex]\hat{R} = R_2 + R_4 || R_1 = 6 \Omega[/tex]
[tex]R_{Th} = R_3 + \hat{R} || R_5 = 8 \Omega[/tex]

The correct answer here should be [tex]2 \Omega[/tex]

From what I remember of this stuff, I agree with your answer of 8ohm. At any rate, surely it cannot be any less than R3, can it? Are you sure you are comparing to the appropriate answer?
 
8ohms look right to me as well.
