An inductive coil has a resistance of $$100 \Omega$$. When an a.c. signal of frequency $$1000 \mathrm{~Hz}$$ is fed to the coil, the applied voltage leads the current by $$45^{\circ}$$. What is the inductance of the coil?
(1) $$10 \mathrm{mH}$$
(2) $$12 \mathrm{mH}$$
(3) $$16 \mathrm{mH}$$
(4) $$20 \mathrm{mH}$$.
