Series Circuit Formula

R_total = R₁ + R₂ + R₃ + ...

In series, resistances add up directly. Same current flows through all resistors.

Series Circuit Properties

  • Same current through all resistors
  • Total resistance = sum of all resistances
  • Voltage divides across resistors
  • Total voltage = sum of voltage drops
  • If one component fails, circuit breaks
