Current Divider Rule
When two resistors are in parallel, current splits inversely proportional to resistance.
Formula
I1 = I_total x R2 / (R1 + R2)
I2 = I_total x R1 / (R1 + R2)
More current flows through the smaller resistance.
Example Calculation
1 A splits between R1 = 100 ohms and R2 = 200 ohms in parallel.
- 01I1 = 1 x 200 / (100 + 200) = 0.6667 A
- 02I2 = 1 x 100 / (100 + 200) = 0.3333 A
- 03Check: 0.6667 + 0.3333 = 1.0 A
