A particular hair dryer is designed to operate in the United States, where electrical outlet voltage is 120V, and its power rating is 1800W. If the heating filament is made of 12-gauge copper wire, which has a diameter of 2.05mm, how long must the filament be? Note that the resistivity of copper is 1.68×10−8Ωm.

Seasoned travelers know that an electrical device that works in one country may not work in another. Imagine taking a 1500 W hair dryer made in the United States, where the rms wall voltage is 120 V, to Australia, where the rms wall voltage is 230 V. Find the power output of the hair dryer when connected to a wall outlet in Australia. (5500W)

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...

Problem 5: Aging Infrastructure [20 points Around the United States, subway systems that were built decades ago are ages. New York, Washington DC, and several other metropolitan areas have experienced recent disruptions in their subway service as a result of outages caused by aging infrastructure. At its core, any subway system is defined by its set of stations and the track segments that connect pairs of stations. Consider the need to intentionally take a segment ofa subway system out of...
