Suppose you need to control the speed of a motor that takes 1200W at full power. This is typical of a big domestic vacuum-cleaner or a washing-machine motor, and is a little more power than a single-bar electric fire uses. First, you try the obvious method: a variable resistor in series, and no other complications. If you adjust the resistor to have a very high value so little current passes, this will make the motor run very slowly or stop....

Question 10 of 20 Which of the following explains why international travelers need to use special adapters when plugging a device designed to operate in the U.S. into a wall outlet in Europe (i.e., Vrms in the U.S. is 120 V, while Vrms in Europe is 240 V)?             The increased voltage causes the device's resistance to increase, and the device won't work.             The increased voltage causes the device's resistance to decrease, and the device will overheat.             The...

Magnets carrying very large currents are used to produce the uniform, large-magnitude magnetic fields that are required for magnetic resonance imaging (MRI). A typical MRI magnet may be a solenoid that is 2.0 m long and 1.0 m in diameter, has a self-inductance of 4.4 H, and carries a current of 750 A. A normal wire carrying that much current would dissipate a great deal of electric power as heat, so most MRI magnets are made with coils of superconducting...

The Three Hills Power Company provides electricity to a large metropolitan area through a series of almost 200 hydroelectric generators. Management recognizes that even a well-maintained generator will have periodic failures or breakdowns. Energy demands over the past three years have been consistently high and the company is concerned over downtime of generators. It currently employs 4 highly skilled and highly paid ($30 per hour) repairpersons. Each works every fourth 8-hour shift, so there is a repairperson on duty 24...
