How large an inductance, in henrys (H), should be connected in series with a 120 V, 60 W lightbulb if it is to operate normally when the combination is connected across a 240 V, 60 Hz line? (First determine the inductive reactance required. You may neglect the resistance of the inductor and the inductance of the lightbulb.)
