Short answer, resistance is for DC, impedance is for AC. So no they aren't the same.
Impedance is an electrical phenomena that is caused by AC circuits.electric resistance - a material's opposition to the flow of electric current; measured in ohms
http://www.princeton.edu/~achaney/tmve/wiki100k/docs/Electrical_impedance.htmlElectrical impedance, or simply impedance, describes a measure of opposition to alternating current (AC). Electrical impedance extends the concept of resistance to AC circuits, describing not only the relative amplitudes of the voltage and current, but also the relative phases. When the circuit is driven with direct current (DC) there is no distinction between impedance and resistance; the latter can be thought of as impedance with zero phase angle.
That's freaking hilarious, because I really didn't notice the face. Proof that a woman with an awesome rack can get away with anything. :laughing:
Well thats not really accurate either, but I was trying to keep it simple for the new guy. Just talking about circuit impedance complex numbers are usually used where Z= R +jZ , phasors can also be used.bkmichael65 said:Close. How about Z=square root of [R squared + (Xl-Xc)squared]
I couldn't figure out how to do the math symbols on this keyboard
