Finding the Norton Equivalent Circuit in a Short Circuited Circuit

Click For Summary
SUMMARY

The discussion focuses on finding the Norton Equivalent Circuit in a short-circuited circuit involving a 2-ohm resistor, a 4-ohm resistor, and a 33 A current source. The user seeks to determine the short circuit current and the Norton resistance using nodal analysis. It is established that both the 2-ohm and 4-ohm resistors, along with the current source, are short-circuited, resulting in zero potential difference between points a and b. The potential difference across the 9-ohm resistor is also questioned, indicating a need for further analysis.

PREREQUISITES
  • Nodal analysis in electrical circuits
  • Understanding of Norton and Thevenin equivalent circuits
  • Basic circuit components: resistors and current sources
  • Ohm's Law and circuit analysis techniques
NEXT STEPS
  • Study the process of finding Norton equivalents in complex circuits

Hi
Can you please tell me how to find the Norton Equivalent or I should say the short circuit current in the attachment diagram?

Norton resistance using two different methods but now question asks me to find resistance by dividing voltage of open circuit which I figure it out over current of short circuit.

What I know is 2 ohm resistor is going to be short circuited but I do not what I should do next, how to write nodal analysis for that?
can I say the 4 ohm and current source also are going to be short circuited or not?
Thanks.

There is a short circuit across both the 2 ohm and 4 ohm resistors and the 33 A current source as they all are connected to a and b. That means zero potential difference between a and b. What is the potential difference across the 9 ohm resistor then?
