What should I do after finding the total impedance?

Click For Summary

Discussion Overview

The discussion revolves around the calculation of power absorbed by a load in relation to the total impedance when the load and source impedances are conjugates. It includes aspects of theoretical understanding and practical application in electrical engineering contexts, particularly focusing on impedance and power calculations.

Discussion Character

  • Homework-related
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant suggests demonstrating that the power absorbed by the load is half the power delivered by the source when the load and source impedances are conjugates.
  • Another participant requests to see the original poster's attempts to solve the problem, emphasizing the importance of personal effort in learning.
  • A participant proposes using the formula for impedances, specifically suggesting Z_Load = R + iX and Z_Source as the conjugate of Z_Load, and asks about the total impedance and total power across the resistances.
  • Multiple participants report obtaining a total impedance of 2R and inquire about the next steps to take regarding power calculations across the impedances.
  • One participant reminds the original poster to adhere to forum rules and encourages them to work through the problem independently, while also noting that hints have been provided by others.

Areas of Agreement / Disagreement

There is no clear consensus on the next steps after finding the total impedance, as participants express varying levels of understanding and readiness to proceed with the calculations.

Contextual Notes

Participants have not fully resolved the mathematical steps needed to calculate the power across the impedances, and there are indications of missing details in the original poster's approach.

show that the power absorbed by the load is half the power delivered by source when the load and source impedances are conjugates.

Please show what you've tried so far. If other people supply your homework answers, you won't end up learning much.
 
I have tried to use the formula of impedences,but still couldnot get it at all.
 
Maybe try with Z_Load = R + iX, and Z_Source as the conjugate of Z_Load?
What is the total impedance?
What is the total power across these resistances?
...Across each?

Answer the above guiding questions (in this forum), and it should help you understand the concept.

Keep on answering the questions!
What is the total power across the impedances?
How much power is across each of the impedances?

And what does this tell you given what Z_source and Z_load are?

We are not going to do your homework for you. Please re-read the Rules link at the top of the thread. And then work on your homework/coursework problem and post your detailed work here.l

You have been given ample hints by the other posters. You should be able to solve this problem now on your own.
