Calculating Current & Power Dissipation in a Circuit Diagram

Click For Summary
SUMMARY

The discussion focuses on calculating total current and power dissipation in a circuit using phasor diagram techniques, specifically avoiding complex numbers. Participants express confusion regarding the application of phasor analysis without complex numbers, particularly in relation to equivalent phasor resistances for capacitors and inductors. The conversation highlights the necessity of converting supply and resistance values into phasor form to apply standard circuit techniques effectively. Clarification on these concepts is essential for accurate circuit analysis.

PREREQUISITES
  • Understanding of phasor diagrams in electrical engineering

Homework Statement




See Attachment.

Find the total Current in the following circuit by phasor diagram techniques only. What is the total power dissipated?Do not use complex #'s.

Homework Equations





The Attempt at a Solution



Im not really sure how to start and the notes for this topic arent that great. I have done a few examples involving a series cct and parallel cct, but I haven't seen one like this.


Any help would be appreciated.
Thanks

EDIT: Could someone move this into engineering/computer science section?

So, what is the equivalent phaser resistances for capacitors and inductors? Once you convert your supply to phaser form, and the resistances to phaser form all of the regular circuit techniques can be applied. I am really confused by the "do not use complex numbers" statement. It's like saying, "You must use phasers! Oh, I'm sorry, I meant phasers without complex numbers (?)."
