Kirchhoff's voltage law
Kirchhoff's voltage law[′kərk‚hōfs ′vōl·tij ‚lȯ]
The law that at each instant of time the algebraic sum of the voltage rises around a closed loop in a network is equal to the algebraic sum of the voltage drops, both being taken in the same direction around the loop. Also known as Kirchhoff's second law.
