How to find Thévenin resistance
Find \$ V_{th} \$: which is basically the voltage across the \$ 12 \Omega \$ :
the circuit is open on the RHS : \$20 V = 20 \Omega \cdot I + (2 \Omega+ 12 \Omega) \cdot 10 I \iff V_{th} = 1.5 V\$

Find current in R1 using Thevenin theorem
There is 10 volts between the left of R1 and the right of R2: -
And clearly (due to the values of R1 and R2 and, RL being disconnected), one-third of 10 volts is across R1. This means that the ...

Thevenized Resistance
From what I see you did not disconnect (remove) the load resistance from the circuit.
Because we want to find the resistance seen by the load resistance. This is why we need to remove it from the ...

How to find Thévenin resistance
The 3Ω solution is correct.
The current source is a dependent type (the symbol doesn't reflect that, but the value does) so you can't just remove it to use superposition you have to write the ...

How to find Thévenin resistance
Welcome. Yes replacing voltage sources by short and current sources with open circuit is correct. One way to determine the Thevenin resistance can be done by applying a test voltage (Vt) at the wanted ...

How to find Thévenin resistance
Hint:
Replace voltage source with short circuit. Leave the dependent current source as it is. Look from the output terminals. Ground the bottom terminal at output. Connect a DC 1A current source ...

Thevenin's theorem and circuit analysis
I'm doing something wrong but I'm not entirely sure what it is
Your first step is sensible and produces this: -
Notice that I've merged the 100 Ω resistor with the 40 Ω resistor because they became ...

Thévenin's theorem exercise with two voltage sources
Thanks to Tyassin I now know what I have done wrong in the superposition theorem. It's V = V1 * R2/(R1+R2) + V2 * R1/(R1+R2) = (V1*R2+V2*R1) / (R1+R2).
To calculate with mesh currents, get the total ...
