What is resonant circuit? and specifically what is RLC circuit?
THANX ALOT!
THANX ALOT!
http://en.wikipedia.org/wiki/ResonantIn an electrical circuit, resonance occurs at a particular frequency when the inductive reactance and the capacitive reactance are of equal magnitude, causing electrical energy to oscillate between the magnetic field of the inductor and the electric field of the capacitor.
Resonance occurs because the collapsing magnetic field of the inductor generates an electric current in its windings that charges the capacitor and the discharging capacitor provides an electric current that builds the magnetic field in the inductor, and the process is repeated. An analogy is a mechanical pendulum.
At resonance, the series impedance of the two elements is at a minimum and the parallel impedance is a maximum. Resonance is used for tuning and filtering, because resonance occurs at a particular frequency for given values of inductance and capacitance. Resonance can be detrimental to the operation of communications circuits by causing unwanted sustained and transient oscillations that may cause noise, signal distortion, and damage to circuit elements.
here is what I think inductors do
they allow current to follow across it and store energy by creating magatic field.
Is this correct, what other basic thing does inductors do?
A resonant circuit is an electrical circuit that contains a capacitor and an inductor, and is tuned to a specific frequency. This frequency is known as the resonant frequency, and is determined by the values of the capacitor and inductor in the circuit.
A resonant circuit works by storing energy in the capacitor and inductor, and exchanging this energy between the two components at the resonant frequency. This creates an oscillating current in the circuit, which can be used for various purposes such as filtering or amplification.
In a series resonant circuit, the capacitor and inductor are connected in series, meaning that the same current flows through both components. In a parallel resonant circuit, the capacitor and inductor are connected in parallel, meaning that the same voltage is applied to both components. This results in different characteristics and applications for each type of circuit.
Resonance is useful in circuits because it allows for the selective amplification or filtering of specific frequencies. This can be used in radio and communication systems to tune in to specific frequencies, or in audio systems to amplify certain frequencies for better sound quality.
Some common applications of resonant circuits include radio and communication systems, audio systems, and power supply systems. Resonant circuits are also used in medical devices such as MRI machines, and in electronic equipment for tuning and filtering purposes.
