Total energy storage in the circuit during resonance

The simplest electrical circuit that exhibits oscillatory behaviour consists of an inductor L and a capacitor C connected in parallel (see Fig. 10.1).Let us assume the initial condition where the capacitor contains q amount of charge, hence the initial voltage V across the LC parallel network is related to the charges as (q=C,V_C = C, v(max )).

Electrical resonance

Resonant circuits can generate very high voltages. A tesla coil is a high-Q resonant circuit.. Electrical resonance occurs in an electric circuit at a particular resonant frequency when the impedances or admittances of circuit elements cancel each other. In some circuits, this happens when the impedance between the input and output of the circuit is almost zero …

15.6: Resonance in an AC Circuit

The resonant frequency for a RLC circuit is calculated from Equation ref{resonantfrequency2}, which comes from a balance between the reactances of the capacitor and the inductor. Since the circuit is at resonance, the impedance is equal to the resistor. Then, the peak current is calculated by the voltage divided by the resistance. …

Parallel Resonance Circuit

The impedance of the circuit is maximum at resonance, and the circuit draws minimum current. At resonance, the circuit''s admittance has a minimum value and impedes the flow of electric current. Unlike the series resonance circuit, the resistors in a resonant condition have the damping effect; thus, the circuit is less selective. (3).

14.5 Oscillations in an LC Circuit

It is worth noting that both capacitors and inductors store energy, in their electric and magnetic fields, respectively. A circuit containing both an inductor (L) and a capacitor (C) can oscillate without a source of emf by shifting the energy stored in the circuit between the electric and magnetic fields.Thus, the concepts we develop in this section are directly …

Simple Parallel (Tank Circuit) Resonance

Plugging in the values of L and C in our example circuit, we arrive at a resonant frequency of 159.155 Hz. What happens at resonance is quite interesting. With capacitive and inductive reactances equal to each other, the total impedance increases to infinity, meaning that the tank circuit draws no current from the AC power source!
