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. ...

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 ...
