Hazel (medicine) and Kirchhoff's circuit rules (sh)


Hazel (medicine)


hazel


1. Consisting of hazels, or of the wood of the hazel; pertaining to, or derived from, the hazel; as, a hazel wand. "I sit me down beside the hazel grove." (Keble)

2. Of a light brown colour, like the hazelnut. "Thou hast hazel eyes."

3. <botany> A shrub or small tree of the genus Corylus, as the C. Avellana, bearing a nut containing a kernel of a mild, farinaceous taste; the filbert. The American species are C. Americana, which produces the common hazelnut, and C. Rostrata. See Filbert.

4. A miner's name for freestone. Hazel earth, soil suitable for the hazel; a fertile loam.

5. <ornithology> Hazel grouse, a European grouse (Bonasa betulina), allied to the American ruffed grouse. Hazel hoe, a kind of grub hoe. Witch hazel. See Witch-hazel, and Hamamelis.

Origin: OE. Hasel, AS. Haesel; akin to D. Hazelaar, G. Hazel, OHG. Hasal, hasala, Icel. Hasl, Dan & Sw. Hassel, L. Corylus, for cosylus.

Kirchhoff's circuit rules (sh)




or Kirchhoff's laws

Two statements, developed by Gustav Kirchhoff, about complex circuits that embody the laws of Conservation (see Conservation law) of electric charge and energy.

They are used to determine the value of the electric current in each branch of the circuit. The first law states that the sum of the currents into a junction in the circuit equals the sum of the currents out of the junction. The second law states that around each loop in an electric circuit, the sum of the electromotive force is equal to the sum of all the potential drops (changes in voltage) across components in the loop. Using these rules, algebraic equations can be formulated to determine the value of currents in different loops in a circuit.
