A three-way lightbulb can produce 50 W, 100 W, or 150 W, at 120 V. Such a bulb contains two filaments that can be connected to the 120 V individually or in parallel (Fig. 19–74). (a) Describe how the connections to the two filaments are made to give each of the three wattages. (b) What must be the resistance of each filament? FIGURE 19–74 Problem 68.
