How to calculate
Split a known total current between two parallel resistive branches.
Branch 1 current = i*b/(a+b) A; Branch 2 current = i*a/(a+b) A; Parallel voltage = i*a*b/(a+b) V
Worked example
Total current (A): 0.03; Branch 1 resistance (Ω): 1000; Branch 2 resistance (Ω): 2000.
Branch 1 current: 0.02 A; Branch 2 current: 0.01 A; Parallel voltage: 20 V.
Assumptions and limits
Uses ideal components and the units shown. This calculation does not establish component ratings, wiring safety or regulatory compliance.

Understanding the result
Split a known total current between two parallel resistive branches.
When this tool is useful
Branch 1 current = i*b/(a+b) A; Branch 2 current = i*a/(a+b) A; Parallel voltage = i*a*b/(a+b) V
