A current divider is a very simple electronics circuit. This provides a current value comparable with other currents. Current divider principle is somewhat similar to a voltage divider.
Current divider formula for two resistors
When have two resistors in parallel, which are subject to the same voltage, it is possible to calculate the current path one of the two resistors.
To calculate one of these two currents ( in our case I1 or I2 ), however, you must know the total current ( here is the current I ) flowing through these resistors and know the value of resistance ( ie, we know the value of R1 and R2 ).
Since these two resistors are subject to the same voltage, then:
Similarly, we can know the voltage U as a function of I1 and R1, which gives:![]()
Using the two formulas above views, we can deduce this formula:
The formula of dividing bridge current is:
