A light dimming circuit has a light bulb in series with an adjustable circuit element: an inductor, capacitor, or resistor. The electrical supply is standard U.S. AC power (120 Vrms, 60 Hz = 377 rad/s). Find the value of the adjustable (a) resistor, (b) inductor, and (c) capacitor that will reduce the power output of the bulb by a factor of 5. You may assume the bulb resistance is not a function of temperature (unlike your experience in lab). The bulb power is 100 W. To get you started: a 100 W bulb has a resistance of 144 ohms. Your solution should include circuit diagrams A light dimming circuit has a light bulb in series with an adjustable circuit element: an inductor, capacitor, or resistor.
