Resistors in Series Calculator

Find total resistance of resistors in series.

Total resistance (Ω) 320

Formula: R = R1 + R2 + R3

Step-by-step with your numbers:

1. Values used:

2. R1 = 100 Ω

3. R2 = 220 Ω

4. R3 = 0 Ω

6. Total resistance = R1 + R2 = 100 + 220 = 320Ω

Did we solve your problem today?

Series resistances simply add up.

The math behind it

R_total = R1 + R2 + R3 + …

100 + 220 → 320 Ω.

Parallel?

Use the parallel calculator — the total is then less than the smallest.
