Circuits in which the inductive reactance equals the capacitive reactance (XL=XC) are called resonant circuits. They can be series or parallel circuits and either RLC or LC circuits. The impedance vector for a typical series RLC resonant circuit is shown in Figure 1 and is summarized as follows: XL and XC are 180 degrees out of phase. XL and XC are equal in value (100 Ω), resulting in a net reactance …
