Series Circuit vs Parallel Circuit — Comparison Table

BasisSeries CircuitParallel Circuit
Current pathSingle path for currentMultiple paths for current
Current flowSame current through all componentsCurrent divides among branches
Total resistanceR total = R1 + R2 + R3...1/R total = 1/R1 + 1/R2 + 1/R3...
Voltage divisionVoltage divides across componentsSame voltage across all components
If one component failsEntire circuit stops workingOther components continue working

Key Points

  • Series circuit has single path; parallel circuit has multiple paths for current
  • Series total resistance increases; parallel total resistance decreases
  • Home appliances use parallel circuits so each can be controlled independently
  • Series circuits are used in decorative lights where failure of one affects all
