Discussion Overview

The discussion revolves around calculating voltage and impedance in AC circuits, specifically using given values for power supply voltage and current. Participants are working through a past exam question and seeking validation of their calculations.

Discussion Character

  • Homework-related

Main Points Raised

  • One participant presents the power supply voltage as E=10e^(jπ/4) [V] and current I1=2e^(jπ/4) [A], asking for assistance in finding voltage V and impedance Z.
  • Another participant reiterates the same question, emphasizing the need to show work for the calculations.
  • A third participant confirms that the work presented looks fine, suggesting that the calculations may be correct.

Areas of Agreement / Disagreement

There is no explicit disagreement noted, but the discussion primarily consists of one participant seeking confirmation on their calculations, with another participant agreeing that the work appears correct.

Contextual Notes

The discussion does not delve into the specifics of the calculations or any assumptions made regarding the circuit parameters.

Who May Find This Useful

Students or individuals studying AC circuit analysis, particularly those preparing for exams or needing clarification on voltage and impedance calculations.

Hi again. I just want to make sure I got the answers correct since this is a past year question (received from a senior), I don't have the answers.

Power supply voltage E=10e^(jπ/4) [V]; Current I1=2e^(jπ/4) [A].
The magnitude of current I2 is equals to current I1, but its phase is π/2 slower than I1.
1) Find the voltage V.
2)Find impedance Z.
