Professor PC Thomas Classes · Answer

(d) : Given power of first bulb, $P_{1}=100 \mathrm{~W}$ and second bulb $P_{2}=40 \mathrm{~W}$\ Current through 100 W bulb, $l_{1}=1 \mathrm{~A}$\ Current through 40 W bulb, $I_{2}=$ ?\ Since both the bulbs are connected in series, the electric current passing through both the bulbs are same i.e., $I_{2}=1 \mathrm{~A}$.\
