| THE CIRCUITS - KIRCHHOFF'S VOLTAGE LAW | ||
In 1847, G. R. Kirchhoff extended the use of Ohm's law by developing a simple concept concerning the voltages contained in a series circuit loop. Kirchhoff's voltage law states: "The algebraic sum of the voltage drops in any closed path in a circuit and the electromotive forces in that path is equal to zero." To state Kirchhoff's law another way, the voltage drops and voltage sources in a circuit are equal at any given moment in time. |
