Computes the quality factor Q = XL / R, which represents the ratio of inductive reactance to resistance. A higher Q indicates a lower energy loss relative to the energy stored in the inductor.

Inputs

Inductive Reactance (XL)(Ω)

Inductive reactance of the coil in ohms

Resistance(Ω)

Series resistance of the inductor in ohms

Results

⚠Resistance must be greater than zero
