Calculation
Rtotal = R₁ + R₂ + R₃
In series, individual resistances add and the same current flows through each part.

Result
Select a target and calculate.
Understand the inputs
- Total resistance Rtotal — Sum of series resistances.
- Resistance R₁ — First resistor.
- Resistance R₂ — Second resistor.
- Resistance R₃ — Optional third resistor; 0 means no third part.
Example
10 Ω + 15 Ω + 5 Ω = 30 Ω.
Assumptions and limits
Ideal ohmic resistors without temperature coefficient.
