Current Divider Calculator

Find how current splits between two parallel resistors.

Current through R₁ (A) 1.5
Current through R₂ (A) 0.5

Formula: I₁ = I·R₂ ÷ (R₁ + R₂)

Step-by-step with your numbers:
1. Values used:
2. Total current = 2 A
3. Resistor 1 = 100 Ω
4. Resistor 2 = 300 Ω
5.
6. Current through R₁ = 1.5A
7. Current through R₂ = 0.5A
Did we solve your problem today?

In parallel resistors, more current flows through the smaller resistance.

The math behind it

I₁ = I·R₂ ÷ (R₁ + R₂). The current splits inversely with resistance.

Worked example

2 A across 100 Ω and 300 Ω → 1.5 A and 0.5 A.

FAQ

Why does the smaller resistor get more?

It offers an easier path, so more current flows through it.
