Two electric bulbs, rated at ($\displaystyle 25$ W, $\displaystyle 220$ V) and ($\displaystyle 100$ W, 220V), are connected in series across a $\displaystyle 220$ V voltage source. If the $\displaystyle 25$ W and $\displaystyle 100$ W bulbs draw powers $\displaystyle P_1$ and $\displaystyle P_2$ respectively, then :
Official answer
(3)
$\displaystyle P_1=16 \mathrm{~W}, P_2=4 \mathrm{~W}$
