Kirchhoff's law

Kirchhoff's law
1. the law that the algebraic sum of the currents flowing toward any point in an electric network is zero.
2. the law that the algebraic sum of the products of the current and resistance in the conductors forming a closed loop in a network is equal to the algebraic sum of the electromotive forces in the loop.
[1865-70; named after G. R. KIRCHHOFF]
