Consider a 760 W light bulb that requires an RMS voltage 21 V to operate normally. How large should an inductance be connected in series with the bulb if the combination is connected across a RMS voltage 255 V, 71 Hz line? (You may neglect the resistance of the inductor and the inductance of the light bulb.)
