Well, I'm really confused.

I simulate a simple serial R-C-L-Network (all in series).

As far as I know the total (input-)Impedance of the network is:

Z = R + jwL - j/(wC) resp. the resonance frequency (where Zin=R) is

1/sqrt(L*C).

At resonance frequency, the Impedance should be real and therefore in

my hummel opinion Voltage and Current schould be in phase.

The funny thing is, when i build up such a network in Schematics

(Cadence PSD 14.1/Orcad 9.2) and simulate it with the PSpice A/D

Simulator, the current is displaced (relative to the voltage) about

lambda/4 - obviously not in phase!?

Can anyone tell my where I made a mistake?

Or why this Problem is showing up?

Thanks to anyone reading this and especially to those who post

answers.
