Current Divider Formula
The following formula is used to calculate the current going through an individual resistor of a series of resistors.
IR = IS * R / Rtotal
- Where IR is the current through the current resistor (amps)
- IS is the source current (amps)
- Rtotal is the total of all the resistors in the series (ohms)
- R is the resistance of the individual resistor (ohms)
Current Divider Definition
A current divider is a circuit that contains a combination of resistors in parallel that effectively splits the current moving through each resistor.
Current Divider Example
How to calculate a current divider
- First, measure the source current
Measure the source current value in Ohms.
- Next, measure the resistance of the individual component
This will be the resistance of the component only, which could be anything from a resistor to a capacitor.
- Determine the total resistance
Add of the total resistance of all of the components in the series
- Calculate the the current
Calculate the current in the individual resistor using the information from steps 1-3 and the equation presented above.
FAQ
A resistor is an electrical component that presents a resistance to the flow of current. It’s typically used to split currents and voltages between pathways.
A current divider is typically a series of resistors set up in parallel that split the current of a source.
