I honestly have no idea how the pythagorean theorem comes in here. Could you show me please?

Could you help me understand where the other impedance comes from? I see that there's one from the inductor but that's all

Oh whoops Irms = 1/2 A. According to the internet, impedances in series just add...maybe I'm missing something here? I don't understand how this works. I thought I had it with Vrms = Irms*z...I don't see where the other impedance comes in

Thank you so so much for replying! So rms current would be P/V = 120/60 = 2 A. Then I'm not sure what to do...I know there's V = L(dI/dt), but will this current vary in time? Or should I use Vrms = z*Irms?

Homework Statement How large an inductance should be connected in series with a 120 volt (rms), 60 watt light bulb if it is to operate normally when the combination is connected across a 240 volt, 60 Hz line? (First determine the inductive reactance required. You may neglect the resistance of...
