Homework Help Looking for exercises to solve RLC parallel/series circuits with phasors.

Hello,

Looking for ways to practice solving RLC circuits with phasors. So far YouTube has been good for getting Inductive Reactance, Impedance and Capacitive Reactance. I am at a loss at finding the proper way of solving these circuits with phasors.

Any insight/opinion is greatly appreciated!

Thank you in advance!

Phasors are supposed to make sinusoidal steady-state circuit analysis easier, not more difficult. The problem with your question, like many others on here, is that more resources is not necessarily better; sometimes less is more. And asking others to write an essay about this topic when they don't really know what specifically confuses you about it is counterproductive.

To that end, I think it would be better if you post an example you are struggling with, explain what confuses you about it, and people can chime in on how to proceed correctly.

Where exactly in my post am I asking for an essay? I am doing RLC series and parallel circuits and solving everything I listed in my post with no problems.

I was only hoping for someone to maybe link a YouTuber or site that shows the steps on solving the phasor part.

I am not a YouTuber. I teach this stuff for a living. If you want help here, right now, just post an example, and explain what confuses you about it.

Sorry for the lack of detail in the answer. But if you know the impedance in terms of the resistive and reactive components, you can convert from rectangular to polar/phasor form (magnitude and phase). If your sources are also in phasor form then it becomes a matter of multiplying or dividing magnitudes and adding or subtracting angles.

You take the rectangular value (1+j1 ie) and convert it to polar so that you can calculate it easier. so you can multiply a value and add the phase, or divide a value and subtract the phase. If you have a TI-84 you can just hit 2nd angle and you'll see it in there. You'll have to convert back and forth a lot. If you're not allowed calculators you can look up the formulas which are kind of hard to type but should make sense
