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
