Summary[edit]
Description47. Кирхофов закон.ogv |
English: Kirchhoff's first law explains currents in a network of conductors having node. It claims that in this case the algebraic sum of currents in the node is equal to zero. In another words, the sum of the currents entering the node is equal to the sum of the currents exiting the node. The circuit in this experiments consists of three branches, with resistor and ammeter in each and denoted respectively. Current flows in the branch R, branching in the R1 and R2 branches. One can see that the sum of the I1 and I2 currents is always equal to the current I. Prepared, performed and explained by Prof. Oliver Zajkov at the Physics Institute at the Ss. Cyril and Methodius University of Skopje, Macedonia.
Français : Démonstration des lois de Kirchhoff à l'aide d'un circuit électrique résistif.
Expérience réalisée et expliquée par le professeur Oliver Zajkov de l'Institut de physique de l'université Saints-Cyrille-et-Méthode de Skopje de Macédoine. Македонски: Првото Кирхоф-ово правило ги поврзува јачините на електричните струи во рагрането струјно коло. Тоа вели дека во јазолот на едно рзагрането струјно коло алгебарскиот збир на јачините на струите кои течат во гранките е еднаков на нула. Поинаку кажано, збирот на јачините на струите кои влегуваат во јазолот е еднаков со збирот на јачините на струите кои излегуваат од јазолот. Струјното коло во експериментот има три гранки. Во секоја од нив се приклучени отпорник и амперметар, обележени соодветно. Струјата тече низ гранката со отпор R и се разгранува во гранки со отпори R1 и R2. Се забележува дека збирот на јачините на струите I1 и I2 е секогаш еднаков на јачината на струјата I. Подготвено, изведено и објаснето од проф. Оливер Зајков на Институтот за физика на Природно-математичкиот факултет во Скопје. |
