L: Inductance (Inductor) - A passive electronic component that stores energy in a magnetic field when electric current flows through it. Measured in Henry (H). Commonly used in filters, oscillators, and power supplies.
F: Farad (Capacitance) - Unit of measurement for capacitance. Represents the ability of a capacitor to store charge per unit voltage. A capacitor with 1F stores 1 Coulomb of charge at 1V. Widely used in timing circuits, filtering, and energy storage.
