Calculadora de Resistencias en Paralelo — Fórmula

Parallel Resistance

Resistors in parallel share the same voltage, and the reciprocals of their resistances add.

Formula

1/R_total = 1/R1 + 1/R2 + ...

For two resistors: R_total = (R1 * R2) / (R1 + R2)

The total is always less than the smallest individual resistor.

Ejemplo Resuelto

Two resistors in parallel: 100 Ω and 200 Ω.

  1. 1/R = 1/100 + 1/200 = 0.01 + 0.005 = 0.015
  2. R = 1 / 0.015 = 66.67 Ω
  3. Or: R = (100 * 200) / (100 + 200) = 20000 / 300 = 66.67 Ω
