Does anybody have access to an AC clamp on current probe for the oscilloscope? I'd like to perform some measurements and see the waveform

What you trying to measure? Resistors reflect the state of both current and voltage...at least that is what they said in school. If you are trying to measure an unknown current all you need to know is the resistor value when you plug it in and use ohms law. All this assumes that you can tap into the lines offcourse.

I am trying to see the specific noise in the current that my circuit generates in the neutral and line side of it, to properly design a choke for that noise.

The circuit is anywhere from 0-120vac rms and the current on it will be up to 0-8.3 Amps

inductor impedince. 1/(2(pi)LF)=xc Do some math and you can rebalance it so that you can get your value of the inductor. A chock is only going to take high noises out. So anything below 60hz might show up. Well actually it might even be a little above 60hz. You should talk to john s or ed.

Thanks for the tip but I mainly want to see the waveform for shits and giggles and to see what it looks like.

p.s. i think you might have your formulas mixed together
the formula for inductive reactance is 2πfl=Xl
And the formula for capacitive reactance is
1/(2πfc)=Xc

Is happyk Adam? If so hows it going man! If not... how's it going unknown man!

Yea this is Adam C
It is and the formula was incorrect. I offten consider xl the same as xc when they are inverse of each other. Btw if you got some time here is an old hackaday link that is kinda intresting. http://hackaday.com/2011/01/14/theory-b ... ess-power/

That's way cool man. I really like it. A buddy of mine is working on a team to build some bike lights and this wireless method would probably solve the problem of the hub.

Earlier designs have used a rotating contact that sucks balls. I will forward this to him. Thanks man!
