Complex Number RLC Series Parallel Voltage and Current Supply

Click For Summary

Discussion Overview

The discussion revolves around the analysis of a complex number RLC circuit involving series and parallel configurations, focusing on the determination of source impedances and the calculation of current I2. Participants are exploring various approaches and formulas related to the circuit's behavior.

Discussion Character

  • Technical explanation
  • Mathematical reasoning
  • Debate/contested

Main Points Raised

  • One participant presents calculations for the source impedances of a current source and a voltage source, questioning the correctness of their results.
  • Another participant asks for clarification on how the value for Xc was determined.
  • Some participants suggest using Kirchhoff's Voltage Law (KVL) in the loop with the voltage source as a potential approach.
  • A participant mentions the formula for Xc, providing a calculation based on frequency and capacitance.
  • There is a discussion about whether the angular frequency should be converted into Hertz, with some uncertainty expressed about the standard form of Omega in the formula.
  • Another participant expresses a belief that conversion may be necessary.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the necessity of converting angular frequency to Hertz, and there is uncertainty regarding the interpretation of the formula involving Omega.

Contextual Notes

Limitations include potential misunderstandings about the standard form of angular frequency and the assumptions made in the calculations for Xc.

Hi Everyone.

I have been looking at this questions for a while now and have just hit a brick wall.

I have found the source impedances using the the following

Z of Current source = 1KΩ - jXC

=1000 - j4000Ω = 4123<-75.96°


Z of Voltage source = 4KΩ + jXL

= 4000 + j1000Ω = 4123<14.04°

Correct ?

But from here I am not sure how to approach determining the current I2.

Any kind of guidance would be greatly appreciated.

Thanks

how did you got your value for Xc ?
 
Plus ! you can use KVL in the loop having voltage source !

Using the following formula:

1/jwC

=1/j(25K rads/sec)(10nF)

Thanks
 
shouldn't the angular frequency should be converted into hz ?
 
I could'nt be sure but I assumse that when the formula states Omega it uses its standard form.
 
i think we need to convert it !
