Determine the Thevenin equivalent with respect to the terminals a,b.
The Attempt at a Solution
Right now I'm just trying to calculate Rth by removing the sources from the circuit. When I calculated the Rth using the node voltage/mesh current method I calculated it to be 20 kΩ.
So right now my idea is I have to short out the voltage source and open the current source.
I think(?) this means the 2kΩ, 20kΩ, and 5kΩ(maybe not) would be cancelled out and the rest of the circuit would be intact.
So I calculated Rth based on the rest...
Can someone explain what I did wrong?
I also tried doing
(10kΩ+50kΩ)||20kΩ+5kΩ which gave me an answer of 20kΩ but I do not think I can add the 5kΩ resistor to the 20kΩ resistor in that order.
