windozeuser Member Nov 14, 2006 #1 I'm currently experimenting with Resonance and LCR circuits. Below is a circuit I'm playing around in with MultiSIM Am I correct in that it will reach resonance at 130Hz? **broken link removed**

C Comcat New Member Nov 14, 2006 #2 I believe it will be resonant at 129949Hz. F(resonance) = 1/2pi((LC)^0.5) NoteLC)^0.5 is another way of stating square root of LC. Using this forum, I didn't know of a way to show a radical sign.

C Comcat New Member Nov 14, 2006 #4 Sorry about that Windozeuser. I calculated using a 10 pF instead of a 10uF capacitor. 130Hz is correct.
