Can a Center Tapped LC Circuit Reduce Potential Difference Across the Inductor?

Click For Summary
SUMMARY

The discussion centers on the feasibility of creating a center-tapped LC circuit that achieves a lower potential difference across the inductor compared to the capacitor, incorporating a spark gap. Participants concluded that in a resonant LC circuit, the voltage across the inductor will always equal that across the capacitor, indicating a fundamental flaw in the proposed circuit design. The conversation also highlighted the challenges of using a power transformer for radio frequency (RF) applications, suggesting that while an RF transformer could theoretically be used, the circuit configuration remains uncertain.

My objective is to make a lc circuit that will have a potential difference across the inductor that is lower than that of the capacitor. A spark gap must also be used. Will this work and will the resonant frequency be the same as if it was wired conventionally?

For a resonant LC circuit, the voltage across the inductor will always equal that across the inductor. I think your circuit is flawed, although I am not certain if you are indicating a power transformer at the bottom, or an RF transformer of some sort.

It is a transformer. So such a circuit is impossible?
 
As it stands at the moment, you are asking radio frequency current to flow through a power transformer.
I think that, in principle, a resonant circuit could have an RF transformer between L and C, but I am still unsure about your circuit configuration because the transformer cannot function for RF.

I see what you are saying now. I'll look into it further and be back. Thank you for your responses..
