What are the 3 series circuit rules?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
- Current is constant: The same current flows through all components (I_total = I₁ = I₂ = I₃)
- Voltage divides: Total voltage equals the sum of individual voltage drops (V_total = V₁ + V₂ + V₃)
- Resistance adds: Total resistance is the sum of all resistances (R_total = R₁ + R₂ + R₃)
These rules make series circuits predictable and easy to analyze.
