Getting Thévenin equivalent when there's a current source only
I am stuck finding the Thévenin voltage in this circuit.
What I did first is remove the current source and replace it with an open circuit. After that I got the Thévenin resistance which is the ...

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 ...

I don't get what I am doing wrong with this Thévenin question [closed]
I understand that the Thévenin voltage is zero because there are only dependent sources, but finding the Thévenin resistance doesn't seem to work.
My work for finding the Thévenin resistance is below. ...

Should resistance between a and b terminals be considered when computing Thévenin-equivalent resistance?
When attempting to find the Thévenin-equivalent circuit to the left of terminals a and b in the image below, should one consider the 4.7 kΩ resistor? Why or why not?
When taking the 4.7 kΩ resistor ...

Thevenin's resistance with a dependant source
I have this circuit for which we must find the Thevenin resistance in considering the load is \$R_L\$. For this case I calculated \$E_{th}=-\beta i_b R_4\$ by shorting the load resistor \$R_L\$ so the ...
