Two light bulbs P and Q are identical in all respects, except that P&#...
Explanation:
When the same potential difference is applied to two light bulbs, the bulb with lower resistance will draw more current and dissipate more power, causing it to shine brighter.
The resistance of a conductor is directly proportional to its length and inversely proportional to its cross-sectional area. Therefore, thicker filaments have lower resistance than thinner filaments.
Reasoning:
P has a thicker filament than Q, which means it has a lower resistance. Therefore, P will draw more current and dissipate more power than Q, causing it to shine brighter.
Q has a thinner filament than P, which means it has a higher resistance. Therefore, Q will draw less current and dissipate less power than P, causing it to shine dimmer.
Answer:
Hence, the correct answer is option A, which states that P will burn brighter because it has the lower resistance.

Because cross-sectional area is inversely proportional to resistance, so if both bulbs have the same potential difference then, the bulb having more cross-sectional area will have low resistance and glow brighter.
