Anyone know about Henry inductors?

Hi,

I have been searching round loads to help me find any info on Henry inductors. I just can't seem to find anything! I am required to find the capacitance required to resonate a 15 henry inductor to 500Hz. Now I can't see how one would do it, one site came up with the equation

XL = 2(pi) x f x L

That seem roughly correct to others?

Accually scrap that, got it I think.

To find the frequency it should be 1 / 2 pi x F x L I think, I should check my notes though as I don't often use tuned circuits (thats what this is right?). I assume its theoretical anyhow, 15H is massive :eek:

This should help anyhow:

EDIT- Yes your right, its a square root, thought there was something different with resonant circuits

cool im doing about this in elec atm.

Its completely theoretical, also the lecturer is useless for electronics. Didn't even know what a Henry was from lectures, had to research it completely. By the way this is for Auto Eng.

Unlucky

. Our electronics lecturer at college was a legend

Henry is the unit for inductance

Say, like a 15mH inductor (15 milliHenrys)

I think that equation stated earlier is correct though.

BTW im a 3rd year elec engineer
