Parallel Resistors Calculator

<-- Enter Resistor Set

You entered a parallel resistor set of {1,5,2,3}
From the 4 numbers you entered, we want to calculate the resistance in ohms, denoted Rt:

The formula for this is as follows:
Rt =1
1/R1 + 1/R2 + 1/R3 + ... + 1/Rn

Calculating our denominator piece, we get:
Calculate R1 denominator piece
R1 = 1
1 ÷ R1 = 1

Calculate R2 denominator piece
R2 = 5
1 ÷ R2 = 0.2

Calculate R3 denominator piece
R3 = 2
1 ÷ R3 = 0.5

Calculate R4 denominator piece
R4 = 3
1 ÷ R4 = 0.33

Our denominator becomes
Denominator = 1 + 0.2 + 0.5 + 0.33
Denominator = 2.3

Our total Resistance is denoted below:
Rt =1
2.3

Rt = 0.52
