Impedence is the opposition to current flow. Impedence is the combination of 3 things. Straight resistance(of the copper itself), Inductive reactance(Back EMF and the like) and Capacitive Reactance. On straight DC, Inductive and Capacitive reactance are non existant, leaving only resistance to oppose the current. Now introduce a variation to the DC waveform, and you introduce Inductive and Capacitive reactance. One thing that has an effect on the ammount of Inductive and Capacitive reactance is the speed or frequency of the variation in voltage. So I was curious is there a set frequency and voltage that is used across the board when stating an impedence. Take a speaker for example, I think 600Hz is used when giving a speaker impedence. This value does not vary from manufacturer to manufacturer. Feel free to correct any of what I have said here Cheers Gabe [Report message to a moderator]
