Electrical resonance occurs in an electric circuit at a particular resonance frequency when the imaginary parts of 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 and the transfer function is close to one.
Resonant circuits exhibit ringing and can generate higher voltages and currents than are fed into them. They are widely used in wireless (radio) transmission for both transmission and reception.
LC circuits
Resonance of a circuit involving capacitors and inductors occurs because the collapsing magnetic field of the inductor generates an electric current in its windings that charges the capacitor, and then the discharging capacitor provides an electric current that builds the magnetic field in the inductor. This process is repeated continually. An analogy is a mechanical pendulum.
At resonance, the series impedance of the two elements is at a minimum and the parallel impedance is at maximum. Resonance is used for tuning and filtering, because it occurs at a particular frequency for given values of inductance and capacitance. It 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.

The beauty of LC Oscillations!
If you connect a charged capacitor across an inductor, you will see a beautiful energy exchange take place between the two elements. These energy oscillations look as if the capacitor is saying: ‘you take the energy’ and the inductor then says: ‘no, you take my energy’. Why don’t any of these elements store the energy and become settled? Let’s have a look at the interesting physics behind these oscillations, and some of the applications.

Resonance in Series AC Circuits
Resonance occurs in AC circuits when reactance is effectively eliminated. This can only happen at a specific frequency for any given inductor and capacitor combination. When the inductor and capacitor are in series, it occurs when their reactances are equal and effectively makes the combined impedance 0 Ohms.
This video shows how to determine the frequency at which resonance occurs and then shows the effect on the voltages across components as well as the real, reactive and apparent power in the system.

Electrical resonance occurs in an electric circuit at a particular resonance frequency when the imaginary parts of 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 and the transfer function is close to one.
Resonant circuits exhibit ringing and can generate higher voltages and currents than are fed into them. They are widely used in wireless (radio) transmission for both transmission and reception.
LC circuits
Resonance of a circuit involving capacitors and inductors occurs because the collapsing magnetic field of the inductor generates an electric current in its windings that charges the capacitor, and then the discharging capacitor provides an electric current that builds the magnetic field in the inductor. This process is repeated continually. An analogy is a mechanical pendulum.
At resonance, the series impedance of the two elements is at a minimum and the parallel impedance is at maximum. Resonance is used for tuning and filtering, because it occurs at a particular frequency for given values of inductance and capacitance. It 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.
