Total Current Calculator – Series Circuit

This calculator determines the total current through any number of resistors in a series configuration.

Series Resistance Calculator


  • Resistor values separated by commas
  • Total voltage across the series resistors

The tool will provide the Total Series Current

Total Current in Series Circuit Formula

Rtotal = R1 + R2 + R3 +…. + Rn

Itotal = V/Rtotal

Example Calculation

Consider four resistors in parallel: 1 Ω, 2 Ω, 3 Ω, 4 Ω and 5 Ω. The total effective resistance is 15 Ω.

For a voltage value of 5V, the total current is 5/15 = 0.33 A
