Capacitors and Inductors

Resistors, with different laws and network theorems, have already been discussed and analyzed in the previous chapters. Like a resistor, capacitor and inductor are also important in the linear circuit elements. Capacitors and inductors do not dissipate energy like resistors, but store energy when these elements are connected to the energy source. Later on, this stored energy can be used for other applications. A capacitor finds its application in power factor improvement, single-phase induction motor starting, filter circuit, laser, electronic flash on a camera, power systems, microphones, tuning circuit of a radio receiver and memory elements in a computer. Similarly, an inductor finds its applications in many areas, namely, in the transformer, power electronic circuit, electrical machines, radio, television and communication systems. This chapter presents, different types of analysis on electric circuits containing capacitors and inductors.
