@Rive is right considering voltage magnitude, but the phase angle might change.Most cases the voltage can be considered as given, so what changes is the current.
Hello to you too and thanks :D.@Rive is right considering voltage magnitude, but the phase angle might change.
@Voltageisntreal , welcome to PF.
You might understand better after reading these two PF Insights articles.
I see, I had gotten confused ! Tyvm :3 :D, I understand now. It does reduce the current, which it would have to because rms is average anyway so the shift wouldn't have affected it.<3.Let's take a simple example. If the PSU in your PC draws 460W, that would mean 2A at 230V.
Of course, PC power supplies has power factor correction these days. Without correction that PSU would draw 575VA (not W, but VA!), in case the power factor // cos(theta) is 0.8.
Since the voltage is the same 230V, it would mean 2.5A current.
So, we can say that in this case the PFC reduced the current to 2A from 2.5A, with the effective power remaining 460W. The very meaning of the PFC is that you modify the cos(theta) from 0.8 to 1 (so theta will change).
PS.: In PC PSUs the correction is done with electronics these days, not with transformers or simple additional inductive/capacitive elements.
