A three-way 240 V lamp bulb that contains two filaments is rated for 200-400-600 W. One filament burns out. Afterward, the bulb operates at the similar intensity (dissipates energy at the same rate) on its lowest as on its highest switch positions however does not operate at all on the middle position. What are the (a) larger and (b) smaller values of the filament resistances?
