Assertion : The 200 W bulbs glow with more brightness than 100 W bulbs.
Reason : A 100 W bulb has more resistance than a 200 W bulb.
Answer & explanation
Correct answer: option 1
$P = \frac{V^2}{R}$
- electric power is inversely proportional to the resistance i.e. more is the resistance less will be the power and vice-versa.
- Since 200 W bulb will have less resistance as compared to 100 W thus it will glow brightly.
