One of the mysteries of the English language finally explained.
Two laws concerning electric networks in which steady currents are flowing. The first law states that the algebraic sum of the currents in all the conductors that meet in a point is zero. The second law states that the algebraic sum of the products of current and resistance in each part of any closed path in a network is equal to the algebraic sum of the electromotive forces in the path.
- ‘For branched cycles, Kirchhoff's law can be applied to calculate the resistance of the complete network, in analogy to its use for electric circuits.’
- ‘Proficiency in analyzing circuits with Kirchhoff's laws, particularly with regard to the sign conventions and with solving simultaneous equations, comes with practice.’
- ‘Since Kirchhoff's laws are derived from general physical properties of electricity, they are applicable to all kinds of electric circuits.’
- ‘In order to quickly measure transmission on any given night, we thus use the alternative approach based on Kirchhoff's law.’
- ‘In working with Kirchhoff's law, positive and negative polarities are assigned in the direction of current flow.’
Mid 19th century: named after G. R. Kirchhoff (see Kirchhoff, Gustav Robert).
