An inductance coil has a reactance of \( 100 \Omega \). When an \( A C \) signal of frequency \( 1000 \mathrm{~Hz} \) is applied to the
\( \mathrm{P} \)
coil, the applied voltage leads the current by \( 45^{\circ} \). The
W
self-inductance of the coil is
(1) \( 1.1 \times 10^{-2} \mathrm{H} \)
(2) \( 1.1 \times 10^{-1} \mathrm{H} \)
(3) \( 5.5 \times 10^{-5} \mathrm{H} \)
(4) \( 6.7 \times 10^{-7} \mathrm{H} \)
