Hello,

Can some one tell me the equation to find capacitor value for series tuned circuit? For an example 2mh inductor, 4khz resonant frequency and then I need to find out the capacitor value. I should write an equation to find capacitor value.

I believe you will benefit from reading the material on RLC circuit here in the AAC ebook.

Thanks,

I guess C = 1 / 4*pi²*F²*L would be correct.

Correct me if I'm wrong

I believe his formula is correct. He's looking for resonance frequency rather than the reactance of a capacitor, the formula is also on here.

Resonance is different from reactance, quite correct.
