Sorry for bad description, it's originally written in Swedish. I try again. Through an inductor (with the resistance of 30 Ohm and inductance of 0,1 H) runs a current with the peak value of 2 A. Calculate the effect factor and the real power if it is connected to the electricity grid. (Which...

Homework Statement An inductor has a resistance of 30 Ohm and an inductance of 0,1 H. A current with the peak value of 2 A runs through. Calculate the effect factor and the active effect if it connects to a grid with 230V and a frequency of 50 Hz. My book says that the effect factor is 0,69...
