My question is similar but I don't have the frequency. I'm given the rectangular coordinates of an RL series circuit which is: 15+j12.56.

I understand that XL = 12.56 and that the formula for XL = (2pi)F(L). I also understand the mechanics of how to perform the calculations. I just don't know how to find the frequency when I'm not given time or omega.

Any help would be greatly appreciated. Thanks!!
