When switching from 2.5kV to 4kV the capacitors once again look like a dead short so now you are applying 1.5kV to a short as compared to the original 2.5kV to a short. Not a huge difference in the

Not relevant because the voltage applied across the short 120 times a second is not very high. _______________________________________________ Amps mailing list Amps@contesting.com http://lists.cont

This mini thread is about a case where the resistance of the inductor WAS significant and possibly DID affect the resonant frequency appreciably. Jim, AF6O ___________________________________________

In what way is the load unbalanced and how would the diodes help? In a series connection all supplies have the same current and each contributes whatever voltage it is set to. How does one get to be

Please explain that more clearly, especially the "opposite sense" part. Are you suggesting that the current somehow flows in the opposite direction through the supply in current limit? Perhaps you me

So you are saying when the voltage drops the load draws more current. What kind of load is that and what is the application? Jim, AF6O _______________________________________________ Amps mailing lis

Needs more refinement! In a parallel tuned circuit containing resistance, Xl and Xc are not equal at the resonant frequency. _______________________________________________ Amps mailing list Amps@con

Well it seems to me that the subject of resonance is about the fact that an oscillation applied to a resonant system produces the greatest effect in that system at a particular frequency. That freque

The problem is your courses only taught a superficial view of the subject based upon approximations. Peter is describing exact circuit analysis results and he is correct. Jim, AF6O __________________

Yes, it's not only possible it is the norm, as has been discussed here endlessly over the years. Only in the case of a series RLC (and a few special cases of parallel circuits) will Xl and Xc be nume

It's OK that you don't have an understanding of the principles of physics as applied to electrical engineering and circuit analysis. Just know that there are limitations to the approximate methods y

An easy answer to your question is a parallel circuit consisting of a series R and L in one branch and a series R and C in the other branch. This circuit has two resistances but your formula only pro
