Series Circuit Calculator
Calculate total resistance, current, and voltage drops in a series circuit. Input your voltage source and resistor values to get instant calculations for your electrical projects.
Step 1: Circuit Specifications
About Series Circuits
In a series circuit, the current is the same through all components. Total resistance is the sum of individual resistances, and voltage divides across resistors proportional to their resistance.
Step 2: Resistor Values
Series Circuit Formulas
Total Resistance: Rtotal = R1 + R2 + … + Rn
Current: I = Vsource / Rtotal
Voltage Drop: Vn = I × Rn

Series Circuit Analysis
Ohm’s Law: V = I × R
Power Formula: P = V × I = I² × R = V² / R
Total Resistance: Rtotal = ΣRi
Voltage Division: Vn = Vtotal × (Rn / Rtotal)
