What is resonance in electrical engineering?

However at resonance there is still current flowing in the inductor, so it will still have a magnetic field. Resonance is commonly encountered in applications like radio tuning circuits and power distribution networks. As the frequency increases, the impedance of the capacitor decreases, so the behaviour of the circuit changes accordingly. In the physics of coupled oscillators, antiresonance, by analogy with resonance, is a pronounced minimum in the amplitude of an oscillator at a particular frequency, accompanied by a large, abrupt shift in its oscillation phase. Resonance happens when the frequency of the initial object's vibration matches the resonant. Here we will discuss only parallel-resonance phenomena, which are the most frequent Resonance is a very valuable property of reactive AC circuits, employed in a variety of applications. Eventually, the input impedance and output impedance are equal. Electric tricycles, or e-trikes, are becoming increasingly popular as an eco-friendly and convenient way to get around.
