Series Resonant Circuit. F r 1 2π lc at its resonant frequency the total impedance of a series rlc circuit is at its minimum. Where zr is the resonance impedance of the circuit.
And finally a series lc circuit with the significant resistance in parallel with the capacitor figure below. The resonant rlc circuits are connected in series and parallel. When a capacitor is charged energy gets stored in static electric field.
It is also called acceptor circuit.
The resonance of a series rlc circuit occurs when the inductive and capacitive reactances are equal in magnitude but cancel each other because they are 180 degrees apart in phase. The sharp minimum in impedance which occurs is useful in tuning applications. We have also seen in our tutorial about series rlc circuits that two or more sinusoidal signals can be combined using phasors providing that they have the same frequency supply. Series resonant circuit with resistance in parallel with l shifts maximum current from 159 2 hz to roughly 180 hz.
