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.
