Current Dividers
Electrical circuits called current dividers are used to divide a current into several channels or branches. They are frequently used to distribute current across multiple components or loads in a variety of applications. Resistors or other impedance components linked in parallel generally make up current dividers.
A current that enters a current divider splits among the many branches according to their individual impedances. A bigger amount of the current will flow via the branch with the lower impedance than it will through the branch with the higher impedance. Ohm’s Law, which says that the current flowing through a component is inversely proportional to its impedance or resistance, is followed in the division of current.
Current Divider Circuit
Kirchhoff’s Current Law and Ohm’s Law combine to provide the current divider equation, which may be used to:
Z_total / Z_i = I_i * Z_total
Where:
The current through the i-th branch is designated as I_i.
The current divider circuit’s overall impedance is represented by Z_total.
The i-th branch’s impedance is Z_i.
I_total represents the whole current flowing into the current divider.
When it’s required to power several components from a single source while preserving particular current ratios, current dividers are frequently utilized in real-world applications. They can be found in power distribution systems, numerous control applications, and electronic circuits.
It’s important to note that current dividers count on the same voltage across all of the branches. This presumption is true if the branches are linked in parallel and experience comparable voltage decreases.

What is a Current Divider?
A current divider is a circuit arrangement used to split an electric current into multiple parallel branches. It is based on the principle that current takes the path of least resistance, and the division of current among the branches is inversely proportional to their resistances. In other words, branches with lower resistance will carry a larger portion of the current.
Components involved in a current divider circuit typically include resistors, inductors, capacitors, transistors, and other electronic elements. By strategically choosing the values of these components, engineers can control and regulate the flow of current within a circuit.
Current Divider Formula
The current division formula is derived from Ohm’s Law, which states that the current passing through a conductor is directly proportional to the voltage applied and inversely proportional to the resistance of the conductor. In a current divider circuit, the formula is expressed as:
