Problem

A tube light of 60 V, 60 W rating is connected across an AC source of 100 V and 50 Hz frequency. Then, (a) an inductance of

\frac{2}{5\pi}

H may be connected in series (b) a capacitor of

\frac{250}{\pi}

\mu\text{F}

may be connected in series to it (c) an inductor of

\frac{4}{5\pi}

H may be connected in series (d) a resistance of 40

\Omega

may be connected in series
