Discussion Overview

The discussion centers on finding Thevenin and Norton equivalents for a circuit where the power source is positioned in the middle, rather than the typical left-hand side placement. Participants explore the implications of this configuration and seek clarification on the validity of rearranging circuit components.

Discussion Character

  • Homework-related, Technical explanation, Conceptual clarification

Main Points Raised

  • One participant expresses difficulty in understanding how to find Thevenin and Norton equivalents when the power source is centrally located in the circuit.
  • Another participant suggests exchanging the positions of a resistor and a current source to place the source on the left side, claiming that the circuit behavior will remain unchanged.
  • A later reply questions the validity of this rearrangement, noting that the circuit appears unchanged.
  • Another participant affirms that the rearrangement is valid, stating that the two components share the same nodal points before and after the exchange, indicating they remain in parallel.

Areas of Agreement / Disagreement

Participants generally agree that the circuit behavior remains unchanged with the proposed rearrangement. However, there is some uncertainty regarding the implications of this change and whether it is universally accepted as valid.

Contextual Notes

Participants do not provide specific details on the assumptions or definitions related to Thevenin and Norton equivalents, nor do they address any potential limitations of the proposed rearrangement.

Who May Find This Useful

Students or individuals studying circuit analysis, particularly those grappling with Thevenin and Norton equivalent circuits in non-standard configurations.

Thevenin/Norton Equivalent,PLEASE HELP!

Hi I apolgise for posting a question which is rather simple but I am struggling to grasp the concept of it,ive done many questions like this before,but this one in particular throws me because the power source is always on the left hand side of the circuit,but in this case its in the middle
Any help would be appreciated,this question has to be done by tomorrow so any replies i will be really grateful,thanks

Question
Find the Thevenin and Norton Equivalent circuits for the circuit shown in the picture
the resistors values are in ohms


Thanks for your time

Exchange the positions of the 20 ohm resistor and the 4 amp current source. The circuit behavior will be the same but the source will be on the left hand side.
 


Thanks very much for the reply

is it valid to do that, i do see the circuit is unchanged.

It is valid since the two share the same two nodal points before and afterwards (i.e. they're still in parallel)
