What is a dividing current?
A dividing current refers to the division of an electric current into two or more distinct paths or branches in an electric circuit. This current division occurs when the circuit contains multiple parallel branches or when circuit components provide different resistance or impedance paths. As a result, the total current entering the circuit is divided between the different branches according to the laws of electrical circuit analysis.
How to divide the current?
Current divides in a circuit due to the principles of Kirchhoff’s current law, which states that the total current entering a junction or node in a circuit must be equal to the total current leaving the junction or node. When a circuit contains parallel branches, the total current entering the junction is divided between the branches in proportion to their respective conductors or impedances. This current division allows each branch to carry a portion of the total current flow, based on its resistance or impedance relative to the other branches.
Does the current divide equally in parallel?
The concept of current divider refers to the mathematical relationship that governs the division of current among parallel branches in an electrical circuit. According to the current divider rule, the ratio of current flowing in each branch is inversely proportional to the resistance or impedance of the branch. In other words, branches with lower resistance or impedance carry more current, while branches with higher resistance or impedance carry less current.
In a series circuit, current divides based on the voltage drop across each component of the circuit. According to Ohm’s law, the current flowing through a series circuit is the same at all points in the circuit. However, the voltage drop across each component in the circuit varies depending on its resistance or impedance. As a result, current divides proportionally between circuit components based on their voltage drops, with higher resistance components experiencing greater voltage drop and lower current flow.
The current divider rule in AC circuits follows the same principles as in DC circuits but takes into account the effects of impedance, reactance and phase angle. In AC circuits, impedance plays an important role in determining current division among parallel branches, with branches offering lower impedance experiencing higher current flow. Additionally, the phase relationship between voltage and current in AC circuits affects current division among branches, especially in circuits containing inductive or capacitive elements.
