The amplitude of the current is maximum. The frequency at which a series LRC circuit reaches resonance is designated as f0.
A periodic variable's amplitude measures the change it undergoes over a single period. When measured against a standard value, a non-periodic signal's amplitude is its magnitude. There are numerous definitions of amplitude, all of which depend on how much the extreme values of the variable differ from one another. The maximum displacement or distance made by a point on a vibrating body or wave relative to its equilibrium position is known as the amplitude in physics. It is equivalent to the length of the vibration path divided in half. Amplitude is the separation between the wave's resting position and its maximum displacement. Frequency is the number of waves that cross a particular point in a second. Period is the length of time it takes for a wave cycle to complete.
