Two bulbs A and B are rated 100 W, 120 V and 10 W, 120 V respectively. They are connected across a 120 V source in series.
Which bulb will consume more power ?

Explanation

Power consumed by the bulb A will be 100 W and by the bulb B will be 10 W as per their rating since both the bulbs operate at their rated voltage (= 120 V). Obviously, the bulb A (with rating 100 W, 120 V) consumes more power than the bulb B (with rating 10 W, 120 V).
