The current divider rule (CDR) is one of most basic rules of Electrical Engineering. Today you'll learn to apply the CDR to four parallel resistors.

Let's consider a circuit with 4 parallel resistors.

The application of CDR in this circuit requires two steps:

Let's consider a circuit with 4 parallel resistors.

The application of CDR in this circuit requires two steps:

- Find the equivalent resistance of four resistors
- Apply the basic CDR formula.

Solving four parallel resistors is very easy and is similar to the two parallel resistors.

Also, learn current divider for three resistors.
