Y to Delta transform with inductors?
Y to Δ conversion formula remains the same for all impedances (\$Z\$). In case the impedance is just a resistor, replace \$Z\$ with \$R\$. In the case of an inductor, replace with \$Z=j L \omega\$. In the case of a capacitor, it must be \$Z=1/(j C \omega)\$. In case of combinations of these elements, add them and replace \$Z\$.
