Great video! Could you explain why, in your load, including a capacitor with the same (but negative) complex component as the thevenin load maximizes power? What's the theory behind that?
If the Thevenin Z is the complex conjugate of the load, then the complex parts cancel, which leaves an impedance minimum. That, in turn, will produce a current maximum. True power is i squared r, thus, you get maximum load power.
Efficiency is defined as the ratio of output (or load) power to the input (or supplied) power, expressed as a percentage. In the case of a reactive AC circuit, remember that true power is only dissipated in the resistive elements. For a deeper dive into this, check out the three videos in the AC Circuit Analysis playlist starting here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-F6rln3zrJXw.html
That's shorthand for 200 ohms resistive (i.e., 200 at an angle of 0 degrees) in parallel with 157 ohms at an angle of 90 degrees. If you're not familiar with phasors and right angle trigonometry, you might try this: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-J3vasJlH8xQ.html and continue from there.
@@rudygomez6996 Go through the AC Circuit Analysis playlist in sequence. Here is the playlist: ru-vid.com/group/PLxuejeK2BP_cIbdalFX_Y9X-nlv2kRxq3 You will get to parallel RLC circuits after about a dozen videos. Don't skip any. Each one builds on the previous video. The playlist follows my free textbook on AC circuit analysis. See the video description for download links.
