Okay, I admit it, I'm a physicist, not an EE, but still ...
An unnamed company in their printed catalog lists the following 2 Variacs
110VAC in, 0-125Vout
Model Capacity (KVA) Max Output Current
#1 .5 2A
#2 2 8A
Now, according to my detailed calculations, 8A x 125V = 1000VA and 2A x 125V
= 250VA
I admit, I never really felt that I understood "power factor" fully, but,
hey, aren't their numbers off by a factor of 2?
Thanks for helping an old fart
