Total Series Resistance
650.00 Ω
Rt = R1 + R2 + R3 + ...
Calculation Steps
  1. 01Series Configuration: Rt = R1 + R2 + R3 + ...
  2. 02Rt = 100 + 220 + 330
  3. 03Rt = 650.000 Ω
REFERENCE — SERIES VS PARALLEL
Series Connection:
R_total = R₁ + R₂ + R₃ + ...
  • • Same current through all resistors
  • • Voltage divides across resistors
  • • Total resistance increases
Parallel Connection:
1/R_total = 1/R₁ + 1/R₂ + ...
  • • Same voltage across all resistors
  • • Current divides between resistors
  • • Total resistance decreases
