An arc lamp requires a direct current of \( 10 \mathrm{~A} \) at \( 80 \mathrm{~V} \) to function. If it is connected to a \( 220 \mathrm{~V} \) (rms), \( 50 \mathrm{~Hz} \) AC supply, the series inductor needed for it to work is close to :
\( \mathrm{P} \)
(A) \( 0.065 \mathrm{H} \)
(B) \( 80 \mathrm{H} \)
(C) \( 0.08 \mathrm{H} \)
(D) \( 0.044 \dot{\mathrm{H}} \)
