Resonance is a phenomenon that occurs in a system when its natural frequency of vibration matches the frequency of an external force applied to it. This causes the system to vibrate with a much larger amplitude than it would at other frequencies, and the energy of the system is concentrated at the resonance frequency.
Resonance is commonly observed in many different physical systems, including mechanical systems (such as a swing), acoustic systems (such as a musical instrument), and electrical systems (such as a circuit).
In electrical circuits, resonance occurs when the inductance and capacitance in a circuit are tuned to the same frequency. This results in a high impedance and a large voltage amplitude at the resonant frequency, which can be used in various applications, including filters and oscillators.
Resonance can also have negative effects, such as in structural engineering where it can lead to the failure of buildings and bridges due to excessive vibrations caused by winds or earthquakes. In electronic circuits, it can cause instability and unwanted noise
