Q. The two bulbs, one of 60W and other 200W are connected in series to a 200 volt line, then
A) The potential drop across two bulbs in the same
B) The potential drop across the 60 W bulb is greater than the potential drop across the 200 W bulb
C) The potential drop across the 200 W bulb is greater than the 60 W bulb
D) The potential drop across both the bulbs is 200 volt
Explanation
(b) In series, the current $I$, is same in two bulbs.
Resistance$R = \frac{V^{2}}{P}$
And potential drop $\ (V) = IR$
$\therefore$ Potential difference across 60 W bulb is greater than the potential difference across 200 W bulb.
