Why Short the 4kΩ Resistor in Source Transformation?

Click For Summary
SUMMARY

The discussion clarifies the process of shorting a 4kΩ resistor in the context of Thevenin equivalent circuits. The 5 mA current source, along with the 16kΩ resistor and the 4kΩ resistor, is transformed into a Thevenin equivalent, allowing for simplification in circuit analysis. This transformation is essential for understanding how to analyze circuits effectively without altering the overall behavior of the circuit.

PREREQUISITES
  • Thevenin's Theorem

Homework Statement


I am a bit confused on why they can just randomly short the 4kΩ resistor, as you can see from the first pic to the second pic.

The Attempt at a Solution

 
Physics news on Phys.org
They didn't just short the 4K resistor. The 5 ma current source, the 16K resistor and the 4 k resistor was made into a norton (or is it thevinin) equivalent.
 
It's Thevinin, I just checked.
