Equations for Combining Capacitors and Inductors Inductors Inductors in Series: LS = L1 + L2 + L3… Combining inductors in series increases total inductance. Inductors in Parallel: Capacitors Capacitors in Series: Capacitors in Parallel: CP = C1 + C2 + C3… Combining capacitors in parallel increases total capacitance. Reactance: Reactance (X) is the opposition of a circuit element to a change in or , due to that element's (L) or (C). The in a capacitor resists change of voltage on the element, the in an inductor resists change of current. The notion of reactance is similar to . Both resistance and reactance are measured in ohms. Inductive Reactance XL : a coil or inductor, as frequency increases, reactance increases.” “For Where: XL = inductive reactance in ohms () 2 6.28 ≈ f = frequency in (Hz) L = inductance in henrys (H) Capacitive Reactance XC : a capacitor, as frequency increases, reactance decreases.” “For Where: XC = inductive reactance in ohms () 2 6.28 ≈ f = frequency in hertz (Hz) C = capacitance in farads (F) Resonance An LC circuit, also called a resonant circuit, tank circuit, or circuit, is an consisting of an and a capacitor connected together. The circuit can act as an electrical , an electrical analogue of a , oscillating at the circuit's . LC circuits are used either for generating signals at a particular frequency, or picking out a signal at
