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 ...

Is there a way to find this resistance? [duplicate]

I have done thevenin analysis on a larger circuit and have gotten the result below. I need to find the value of RL. Would I use thevenin again? But that would give me the same result because I would ...

Thevenin's equivalent of Wheatstone bridge

I tried to calculate the Vos and Isc and both of them are zero..so the Thevenin's resistance is 0/0=undefined. How do I calculate the resistance when Vos/Isc fails,such like the Wheatstone bridge?...

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 ...

What is the difference between the substitution principle and Thevenin theorem?

The substitution principle (as seen in this book; in italian, sorry) Let A and B be any two part of an electrical network with voltage and current sources and only resistances, connected by ...
