áramosztók

Áramosztók, also known as current dividers, are passive electronic components that split an electrical current into different paths. The principle behind an áramosztó is based on Kirchhoff's current law, which states that the algebraic sum of currents entering a node (or junction) must equal the algebraic sum of currents leaving that node. In a simple áramosztó, a current entering a junction will divide among the branches connected to that junction. The proportion of current flowing through each branch is inversely proportional to the impedance of that branch. Branches with lower impedance will draw more current, while branches with higher impedance will draw less.

The impedance of each branch can be determined by the resistance, capacitance, or inductance of the components within that branch. In a purely resistive áramosztó, the current division is straightforward and depends solely on the resistances of the parallel resistors. For more complex circuits involving reactive components, the impedance will be frequency-dependent, meaning the current division will also vary with the frequency of the input signal. Áramosztók are fundamental in circuit analysis and are used in various applications, including current sensing, signal splitting, and impedance matching. Understanding how current divides is crucial for designing and troubleshooting electronic circuits.
