| Quality Factor (Q) : Quality factor of an inductor or capacitor. It is the ratio of a component?s reactance (energy stored) to its effective series resistance (energy dissipated).
| | Quantum Mechanics: The laws of physics that apply on very small scales. The essential feature is that electric charge, momentum, and angular momentum,as well as charges, come in discrete amounts called quanta. | | Quantum: The smallest discrete amount of any quantity (plural: quanta). | | Quark (q): A fundamental fermion that has strong interactions. Quarks have electric charge of either +2/3 (up, charm, top) or -1/3 (down, strange, bottom) in units where the proton charge is 1. | | Quaternary: A coding scheme that uses four different voltage levels to represent information, used over tha local loop with basic ISDN |
