Hi All, I thought some of you might find my technical article of the month interesting. It is on making voltage measurements with a current probe. Over much of the useful frequency range of a current probe, its output is not the current in the wire but rather the voltage drop along the wire per unit length. The waveshape of the probe output is that of the voltage drop along the wire (di(i)/dt), not the current in the wire (i(t))!
If this sounds interesting, click on the current probe picture at the bottom of the index page on my website at http://emcesd.com for a technical discussion along these lines.
