120 V 60 Hz. What must be the maximum inductance
value if you want to dim the lights down to 1/5 of their intensity. What if instead of an inductor
you used a resistor what must be the value of the resistor to dim the lights down to 1/5. Assume
the light bulb behaves like an ohmic resistor throughout. Note more than one steps are needed
to solve this! (Ans: 76.4 mH, 17.8 Q)
