How Do You Approach Source Transformation in This Circuit?

Click For Summary
SUMMARY

This discussion focuses on the approach to source transformation in a specific electrical circuit involving a 5A current source and a -9V voltage source with two 4-ohm resistors. The key conclusion is that starting from the left side of the circuit simplifies the analysis, as the -9V source dictates the node voltage, rendering the +9V source irrelevant. Participants emphasize the importance of understanding circuit placement post-transformation to avoid confusion in series and parallel configurations.

PREREQUISITES
  • Understanding of source transformation techniques in circuit analysis
  • Familiarity with Ohm's Law (v = r * i)
  • Basic knowledge of series and parallel resistor configurations
  • Ability to analyze circuit diagrams and identify fixed voltages
NEXT STEPS
  • Study the principles of source transformation in electrical circuits
  • Learn about analyzing circuits with multiple sources and resistors
  • Explore advanced circuit analysis techniques such as nodal and mesh analysis
  • Practice solving circuit problems involving both current and voltage sources
USEFUL FOR

Electrical engineering students, circuit designers, and anyone involved in circuit analysis and design who seeks to improve their understanding of source transformation techniques.

Homework Equations



v = r * i


The Attempt at a Solution



Having issues with the left box I think. I have been starting on the right side and working left by first starting with the 5A current source. I guess I'm having issues with the circuit placement after the transformation and how it ends up turning out once you get to the left box which I believe isn't in series at all.

It's actually more straightforward to start from the left. The left most source (+9V with two 4 ohm resistors) can be eliminated because the -9V voltage source will force the node to a fixed voltage no matter what the +9V source current is.
