Hi!

Yes! In a.c. analyses all valus (current) must be in RMS. They are
represented as vector, bay Real and Imaginar component.

Zadeva: [femm] Power Losses


I have been using FEMM 3.1 to calculate r.f. losses in
solenoids. I made each turn a separate circuit, and defined
a current of 1-Ampere. I started by assuming that with I=1,
I2*R=R, and hence P=R. I found I was getting resistance
values ~ 1/2 what I expected. It finally dawned that with
a.c. analyses, the defined current must be treated as an
r.m.s value. Can someone confirm I am right, or have I
dropped a factor two somewhere else?
