Parallel Resistor Calculator

Parallel Resistor Calculation

Resistor R₁

Ohms

Resistor R₂

Ohms

Parallel Resistance R_p

Ohms

This calculator calculates the parallel resistance rp using resistor r1, resistor r2 values.

R_p = 1 / ((1/R₁) + (1/R₂))

Where,

R_p = Total Parallel Resistance
R₁ & R₂ = Resistors connected in parallel
