1. Tank Circuit & Resonance

2. Parallel Resonance

3. Tank Circuit This circuit stores energy in the form of electric and magnetic fields so it is a tank (storage) of energy. Inductor stores energy in the form of magnetic field and capacitor stores energy in the form of electric field. Inductor and Capacitor play catch-catch of energy by energizing and de- energizing

5. Effect of winding Resistance on the parallel resonant frequency Quality Factor is the ratio of the reactive power in an inductor to the true power in the winding resistance R W of the coil or the resistance in series with the coil It is called unloaded Q because it is defined with no load across the coil.

6. When the winding resistance is considered, the resonant condition is given as OR

8. For most practical situations, the approximate formula is sufficient given by Contents of this presentation were taken from Principles of Electric Circuits 8 th Edition By Floyd

10. This stray capacitance may become significant especially at high frequencies
