4. R-L-C Circuits and Resonance
CHAPTER OBJECTIVES
After carefully studying this chapter, you should be able to do the following:
➢State the condition of resonance in an R-L-C series circuit.
➢Explain the effect of variation of frequency of supply voltage on the current, power factor, and voltage drops in an R-L-C series circuit.
➢Explain how R-L-C series circuit at resonance can be used as filter element.
➢Explain with the help of an example the application of R-L-C series resonant circuit.
➢Explain the meaning of half-power frequencies.
➢Define quality factor of a series resonant circuit.
➢Draw and explain selectivity curve and bandwidth of a series resonant circuit.
➢Establish relationship between bandwidth and quality factor.
➢Explain how ...
