Parallel Resistors Calculator

Resistance of Parallel Connected Resistors Calculator

Formula & Equations for Parallel Resistors Calculator

Finding Total Resistance (R_T) when R₁ and R₂ are given;

1/R_T = 1/R₁ + 1/R₂

R_T = R₁||R₂

R_T = R₁ x R₂ / (R₁ + R₂)

Finding R₁ when R_T and R₂ given;

R₁ = R₂× R_T / (R₂ – R_T)

Finding R₂ when R_T and R₁ given;

R₂ = R₁ × R_T / (R₁ – R_T)
