Kirchhoff's laws

/ˈkɜkɒfs lɔz/ (say 'kerkofs lawz)

plural noun Physics two laws relating to electrical circuits which state:
1. that in any network of wires the algebraic sum of the currents which meet at a point is zero.
2. that the algebraic sum of the electromotive forces in any closed circuit is equal to the algebraic sum of the products of the resistances of each portion of the circuit and the currents flowing through them.
{from Gustav Robert Kirchhoff, 1827–87, German physicist}
