7 Suppose that two ac waves have the same frequency but differ in phase by exactly 1 20 of a cycle What is the phase difference between these two waves (a) 18 (b) 20 (c) 36 (d) 573 8 Suppose an ac signal has a frequency of 1770 Hz What is its angular frequency (a) 1770 rad/s (b) 11,120 rad/s (c) 282 rad/s (d) Impossible to determine from the data given 9 A triangular wave exhibits (a) an instantaneous rise and a defined decay (b) a defined rise and an instantaneous decay (c) a defined rise and a defined decay, and the two are equal (d) an instantaneous rise and an instantaneous decay 10 Three-phase ac (a) has sawtooth waves that add together in phase (b) consists of three sine waves in different phases (c) is a sine wave with exactly three harmonics.

You might wonder why ac is even used Isn t it a lot more complicated than dc Well, ac is easy to generate from turbines, as you ve just seen Rotating coil-and magnet devices always produce ac, and in order to get dc from this, rectification and filtering are necessary These processes can be difficult to achieve with high voltages Alternating current lends itself well to being transformed to lower or higher voltages, according to the needs of electrical apparatus It is not so easy to change dc voltages Electrochemical cells produce dc directly, but they are impractical for the needs of large populations To serve millions of consumers, the immense power of falling or flowing water, the ocean tides, wind, burning fossil fuels, safe nuclear fusion, or of geothermal heat are needed (Nuclear fission will work, but it is under scrutiny nowadays because it produces dangerous radioactive by-products.

(d) is of interest only to physicists 11 If two perfect sine waves have the same frequency and the same amplitude, but are in opposite phase, the composite wave (a) has twice the amplitude of either input wave alone (b) has half the amplitude of either input wave alone (c) is complex, but has the same frequency as the originals (d) has zero amplitude (that is, it does not exist), because the two input waves cancel each other out 12 If two perfect sine waves have the same frequency and the same phase, the composite wave (a) is a sine wave with an amplitude equal to the difference between the amplitudes of the two input waves (b) is a sine wave with an amplitude equal to the sum of the amplitudes of the two original waves.

) All of these energy sources can be used to drive turbines that turn ac generators Technology is advancing in the realm of solar-electric energy; someday a significant part of our electricity might come from photovoltaic power plants These would generate dc Thomas Edison is said to have favored dc over ac for electrical power transmission in the early days, as utilities were first being planned His colleagues argued that ac would work better It took awhile to convince Mr Edison to change his mind He eventually did But perhaps he knew something that his contemporaries did not foresee There is one advantage to direct current in utility applications This is for the transmission of energy over great distances using wires Direct currents, at extremely high voltages, are transported more efficiently than alternating currents.

transmitted signal diminishes according to the square of the distance. A signal measured at 20 watts and one mile from the transmitter will be one quarter that strength, or five watts, at two miles from the transmitter. When Edwin Armstrong (refer to 1, First Things First ) announced and demonstrated his invention of frequency-modulated radio in 1935, he turned the broadcast industry on its ear. He offered a technology that not only eliminated the random noise and static that plagued AM radio, but also lowered transmitter power requirements and improved the capability of receivers to lock onto a weak signal. World War II provided an ideal testing ground for FM. AM radio, used universally by the Axis powers during the war, was easily jammed by powerful Allied transmitters. FM, on the other hand, used only by Allied forces, was unaffected by AM jamming techniques. As we mentioned earlier, many historians believe that FM radio was crucially important to the Allies success in World War II.

(c) is not a sine wave, but has the same frequency as the two input waves (d) has zero amplitude (that is, it does not exist), because the two input waves cancel each other out..
