Current Divider Calculator
When current reaches a junction of two parallel resistors it splits between them, and more of it flows through the smaller resistance. This calculator applies the current divider rule to tell you exactly how much goes down each branch. For two parallel resistors, the current in one branch equals the total current times the opposite resistor divided by the sum of both resistors. Enter the total current entering the node and the two resistor values, and the tool returns the current in each branch, confirming that the two add back up to the total. This is a everyday tool for analysing sensor networks, meter shunts, and any point where a current fans out across parallel paths. It complements the voltage divider, which splits voltage across series resistors instead. Enter your values and read the split instantly. Everything runs locally in your browser, so it is fast and private.
How to use Current Divider Calculator
- Enter the total current entering the parallel node.
- Enter the two parallel resistor values in ohms.
- Read the current flowing through each branch.
- Confirm the two branch currents sum back to the total.
Frequently asked questions
How does the current divider rule split current?
For two parallel resistors, the current in one branch equals the total current times the opposite resistor divided by the sum of both resistors.
Which branch carries more current?
The lower resistance branch carries more current, since current prefers the path of least resistance, and the tool shows this split explicitly.
Does the branch current depend on voltage?
You do not need the voltage; the divider rule uses only the total current and the two resistor values to find each branch current.
