Resistors in an AC circuit, capacitors in an AC circuit, inductors in an AC circuit, the RLC series circuit, power in an ac circuit, resonance in a series rlc circuit, the transformer,. As the main contents of the document "Alternating current circuits and electromagnetic waves". Invite you to consult. | Arecibo a large radio telescope in Puerto Rico gathers electromagnetic radiation in the form of radio waves. These long wavelengths pass through obscuring dust clouds allowing astronomers to create images of the core region of the Milky Way Galaxy which can t be observed in the visible spectrum. CHAPTER Alternating Current Circuits and Electromagnetic Waves Every time we turn on a television set a stereo system or any of a multitude of other electric appliances we call on alternating currents AC to provide the power to operate them. We begin our study of AC circuits by examining the characteristics of a circuit containing a source of emf and one other circuit element a resistor a capacitor or an inductor. Then we examine what happens when these elements are connected in combination with each other. Our discussion is limited to simple series configurations of the three kinds of elements. We conclude this chapter with a discussion of electromagnetic waves which are composed of fluctuating electric and magnetic fields. Electromagnetic waves in the form of visible light enable us to view the world around us infrared waves warm our environment radio-frequency waves carry our television and radio programs as well as information about processes in the core of our galaxy. X-rays allow us to perceive structures hidden inside our bodies and study properties of distant collapsed stars. Light is key to our understanding of the universe. RESISTORS IN AN AC CIRCUIT An AC circuit consists of combinations of circuit elements and an AC generator or an AC source which provides the alternating current. We have seen that the output of an AC generator is sinusoidal and varies with time according to Av Ahmaxsin 2 ft where Av is the instantaneous voltage A vmax is the maximum voltage of the AC generator and f is the frequency at which the voltage changes measured in hertz Hz . Compare Equations and with Equation . We first consider a simple OUTLINE Resistors
