Applications of Series Resonance Circuit: They are used for Tuning purpose. The series resonance current curve increases to a maximum at resonance then decreases as resonance is passed. The electrons in these pi orbitals will be spread over more than two atoms, and hence are delocalized. Resonance frequency: When a material oscillates at a high amplitude at a specific frequency, this is referred to as resonance. 11 = 2.00 A 9.1 kQ (4) Series Resonance circuits are used in the communication system for signal processing.
