LC VOLTAGE The impedance of an inductor and a capacitor in series, Z series ​ , is given by Z series = (Xc−Xl) Where Xc = 1 / 2(pi)FC The Resonant Frequency (F) of an LC circuit in series is given by Ohm’s Law for an LC circuit in series is given by V t = IZ LC VOLTAGE The voltage across the inductor (c) or capacitor ( ER of t ) is greater than the applied voltage (h). At frequency close to resonance , the voltage across the individual components is higher than the applied voltage (h), and, at resonant frequency, the voltage VT ​ across both the inductor and the capacitor are theoretically infinite . However, physical constraints of components and circuit interaction prevent the voltage from reaching infinity. The voltage ( V L ​ ) across the inductor (C) is given by the equation: ​ ​
