Enter Resistor Set

You entered a parallel resistor set of

{1,3,5}

calculate the resistance in ohms, denoted R_t

The formula for this is as follows:

R_t =	1
	1/R₁ + 1/R₂ + 1/R₃ + ... + 1/R_n

Calculating our denominator piece, we get:

R₁ = 1

1 ÷ R₁ = 1

R₂ = 3

1 ÷ R₂ = 0.33333333333333

R₃ = 5

1 ÷ R₃ = 0.2

Our denominator becomes

Denominator = 1 + 0.33333333333333 + 0.2

Denominator = 1.5333333333333

Our total Resistance is denoted below:

R_t =	1
	1.5333333333333

R_t = 0.65217391304348

You have 1 free calculations remaining

What is the Answer?

R_t = 0.65217391304348
