duality principle

[dü′al·əd·ē ‚prin·sə·pəl] Also known as principle of duality. (electricity) The principle that for any theorem in electrical circuit analysis there is a dual theorem in which one replaces quantities with dual quantities; current and voltage, impedance and admittance, and meshes and nodes are examples of dual quantities. (electronics) The principle that analogies may be drawn between a transistor circuit and the corresponding vacuum tube circuit. (electromagnetism) The principle that one can obtain new solutions of Maxwell's equations from known solutions by replacingEwithH, Hwith-E,ε with μ, and μ with ε. (mathematics) A principle that if a theorem is true, it remains true if each object and operation is replaced by its dual; important in projective geometry and Boolean algebra. (quantum mechanics) wave-particle duality
