Current divider calculator

Example I1 = 8.246 mA through R1 — I2 = 1.754 mA through R2

Formula

I_{1} = I_{in} \times \frac{R_{2}}{R_{1} + R_{2}}

With the default values

8.246 mA = 10 mA \times \frac{4.7 kΩ}{1 kΩ + 4.7 kΩ}

Two parallel resistors split an incoming current in inverse proportion to their resistance — the smaller resistor carries the larger share. $I_{1} = I_{in} \times \frac{R_{2}}{R_{1} + R_{2}}$

What you enter

Iin (A)
R1 (Ω)
R2 (Ω)
