A series R-L-C circuit is an electrical circuit that consists of a resistor (R), an inductor (L), and a capacitor (C) connected in series. When AC voltage is applied to this circuit, it exhibits certain properties of resonance, which are important in understanding its behavior. Resonance occurs when the impedance of the circuit is minimized, resulting in a maximum current flow at a specific frequency. Here are the key properties of resonance in a series R-L-C circuit:
Resonant Frequency (fâ): The resonant frequency is the frequency at which the impedance of the circuit is at its minimum value. In a series R-L-C circuit, the resonant frequency is given by the formula:
fâ = 1 / (2Ďâ(
