Electrical resonance is a phenomenon that occurs in an AC circuit when the inductive reactance (XL) and capacitive reactance (XC) cancel each other out, resulting in a significant increase in current flow at a specific frequency. This particular frequency is called the resonant frequency.
Imagine a swing set. When you push someone on a swing at just the right timing (matching the swing's natural frequency), you can make them swing higher and higher with each push. Similarly, in an electric circuit, an AC voltage applied at the resonant frequency can cause the current to resonate, significantly amplifying it.
