The unit of `L//R` is (where `L=` inductance and `R=` resistance)

The ratio L//R , where L and R stand for Inductance and Resistance, has the same dimensions as those of

Self inductance || L-R Circuit

An oscillating circuit consists of two coils connected in series whose inductances are L_(1) and L_(2) active resistances are R_(1) and R_(2) , and mutual inductance is negligible. These coils are to be replaced by one, keeping the frequency and the quality factor of the circuit constant. Find the inductance and the active resistance of such a coil.
