Current Divider in Electronic Circuit

Circuits-Current Divider

Current Divider is a simple linear circuit or device which divides the total input current to various paths or loads in fractions of the input current.It can be used to divide the input current in fractions to various branches on the device in a certain ratio.

A current divider circuit is a circuit which divides the input current to various branches in a certain ratio. A simple arrangement of two or more resistors in parallel can be considered as a current divider Circuit. A current divider circuit contains various impedance in parallel.
Current Divider Rule:
The Current Divider Rule is the rule which determines how much Current flows through each branch in a current divider.

The general form of the Current Divider Rule is:

Where ,

= The current flowing through the required branch.

= Total Current flowing through the current divider or the array of resistors.

= The Total resistance of the current divider or the array of resistors.

= Resistance of the required branch.

Proof:

Let us consider following current divider with two resistors in parallel:

Here,

= Total Resistance of the current divider = =

And ,



Now Taking,



Thus,



And Similarly:



Now , Let us consider following current divider with three resistors in parallel:

Here,



= Total Resistance of the current divider = =

And ,



Now Taking,



Thus,



And Similarly:

,
Note: A Current Divider is not equivalent to a Current Regulator and is designed for a specific purpose or circuit so is Circuit or Purpose dependent.
