A light dimmer consists of a variable inductor connected in series with a 100 W lightbulb. This simple circuit is supplied with 120 V (rms) at 60 Hz. The inductor can be adjusted to any value between zero and L max . What value of L max would let the dimmer vary the power dissipated by the bullb by a factor of 5.00 ? (Ignore the temperature‑dependance of the lightbulb's resistance.)
