You plan to take your hair blower to Europe, where the electrical outlets put out 240 Vinstead of the 120 V seen in the United States. The blower puts out 1600 W at 120 V . What could you do to operate your blower via the 240 V line in Europe? What current will be drawn from the 240 V line when the dryer is connected to the 120 V side of the transformer? What resistance connected directly to the...
