Thevenin's Resistance
I can't understand why the answer is like in the picture and not R = [ ( 4 + 6 ) // 8 ] + 2.
Isn't 4 in series with 6 and parallel to 8 ?

Calculate the thevenin resistance with diagonal resistors
The question is:
Replace the circuit with a Thevenin Equivalent Circuit and find the Thevenin Resistance (Rt) in ohms and find the current in R3.
I've used Thevenin before and solved quite a few ...

AC analysis: finding L and R
EDIT: there should be arg[I2] instead of arg[I3]
I've tried to replace V1, C1, R1 with Thevenin equivalent, but I've lost in my calculations. Is there any better approach?

Confusing Parallel/Series Arrangements in Application of Thévenin's Theorem
I'm learning from Paul Scherz's Practical Electronics for Inventors (2nd ed.) and I've become confused at what was I thought I was comfortable with: namely parallel and series resistors. The offending ...

How to find Thévenin voltage with dependent voltage source
I am not an electrical engineer, so I lack fundamentals. I was trying to solve for the Thévenin voltage, that is Vout at the open terminals A and B, but what makes it significantly difficult for me is ...

Why do we treat R1 and R2 as though they're parallel in this circuit?
I'm working on a homework problem and I need to solve for the base current Ib, and I know to do that I need to find the Thevenin equivalent at the transistor base. My professor solves for it as though ...

Conceptual Question About Hemholtz-Thévenin Theorem
I've been taught that for the Hemholtz-Thévenin's method I need to add an independent voltage source with a current flowing and at the same time "turn off" independent sources of voltage and current ...

Finding the Thevenin equivalent circuit for the following one
From my poor drawing , it's obvious that the resistance between A and B terminal is just
$$((((((100 || 100)+30) ||80)+20)||60)+20) = 50\Omega$$
But I am getting confused about determining the ...

Idea behind Thevenin equivalent circuit
As i know, we find a thevenin equivalent resistance by finding open-circuit voltage and short-circuit current and then divide these two. I have looked on wikipedia and other sources but could not find ...
