The tool will provide the Total Series Current

**Total Current in Series Circuit Formula**

**R _{total} = R_{1} + R_{2} + R_{3 }+…. + R_{n}**

**I _{total} = V/R_{total}**

**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
