Resonant circuits | Brilliant Math & Science Wiki

Resonance occurs in a circuit when the reactances within a circuit cancel one another out. As a result, the impedance is at a minimum and the current is at a maximum.Mathematically, the condition for resonance is [X_L = X_C.] Resonance allows for the maximum power output of an RLC circuit.. The current in a circuit peaks at the resonant frequency.

LC Circuit | Overview & Research Examples

LC circuit (aka tank or resonant circuit)

This all makes sense. If current was still flowing then the capacitor wouldn''t be fully charged -- its charge would be changing. But once it''s charged, there''s nothing keeping it charged and so that charge circulates back through the circuit, providing the current.

Q Factor and Bandwidth of a Resonant Circuit

The Q, or quality, factor of a resonant circuit is a measure of the "goodness" or quality of a resonant circuit. A higher value for this figure of merit corresponds to a more narrow bandwidth, which is desirable in many applications.

14.6: 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 applicable to the …

Simple Parallel (Tank Circuit) Resonance

Resonance in a Tank Circuit. A condition of resonance will be experienced in a tank circuit when the reactance of the capacitor and inductor are equal to each other. Because inductive reactance increases with increasing frequency and capacitive reactance decreases with increasing frequency, there will only be one frequency where these two reactances will be equal.

8.2: Series Resonance

Refining Series Q. As noted in Chapter 2, all inductors have some series resistance associated with them, usually called (R_{coil}). This resistance needs to be included as part of the overall circuit resistance, adding to whatever other series resistance exists.

Resonant RLC Circuits

Resonance. Resonance in AC circuits implies a special frequency determined by the values of the resistance, capacitance, and inductance.For series resonance the condition of resonance is straightforward and it is characterized by minimum impedance and zero phase. Parallel resonance, which is more common in electronic practice, requires a more careful definition.

LC Circuit | Overview & Research Examples

31.1.2. All four quantities vary sinusoidally. In an actual LC Circuit, the oscillations will not continue indefinitely because there is always some resistance present that will drain energy from the electric and magnetic fields and dissipate it as thermal energy (the circuit may become warmer).The oscillations, once started, will die away as Fig. 31.1.3 sug- gests.
