Op amp difficulties

ABSOLUTELY NOT SO. Ohms law does apply. The point is that reactance and resistance are losses in circuit and work perfectly as long as you take into consideration the frequency of the AC current or volatge, a 1 ohm reactance will drop the same voltage as a 1 ohm resistor providing that you measure the drop at the frequency where the reactive component = 1 ohm. A resistance of 1 ohm will drop the same voltage with ac or dc. A reactance is C or L taken singly or combinations of both Vs frequency i.e. XL = 2Pi * F * L so a 1Hy coil has a reactance of 6.28 ohms at 1 Hz and a capacitor has an XC of 1/6.28 * F * C, so a 1 F capacitor has a reactance of of .15915 ohms at 1 Hz. Resonance is the point where XL = XC. The difference between XL and XC is the phase angle as a capacitor's instantaneous output current leads its voltage output and an inductor's current lags it's output voltage. At resonance the impedance is a very low value in a series configuration and a very high value in a parallel circuit. Attempting to explain more Basic AC Theory is I think beyond the scope of this forum. IMO
