Problem

A tube light of rating

60\text{ V},\ 60\text{ W}

is connected across an AC source of

100\text{ V}

and frequency

50\text{ Hz}

. Then, (a) An inductance of

\dfrac{2}{5\pi}\text{ H}

may be connected in series. (b) A capacitor of

\dfrac{250}{\pi}\,\mu\text{F}

may be connected in series with it. (c) An inductance of

\dfrac{4}{5\pi}\text{ H}

may be connected in series. (d) A resistance of

40\,\Omega

may be connected in series.
