Two electric bulbs a and b rated 200v 100w
WebKCET 2004: Two electric bulbs A and B are rated as 60 W and 100 W. They are connected in parallel to the same source. Then, (A) both draw the same cur WebBeing in series, the same current passes through both the bulbs. Power consumed in bulbs A = P A = i 2 R A = (0.076) 2 × 144 = 0.8317 W. Power consumed in bulbs B = P B = i 2 R B = (0.076) 2 × 144 = 8.317 W. This clearly shows that P A < P B i.e., bulb B (10W, 120 V) consumes more energy when these are connected series.

The answer is option B. Note: If two bulbs have the same voltage rating but the power is different, then a bulb having high power will have low resistance. And the low power bulb will fuse than the high power ...
WebJun 19, 2024 · In case of Bulb 1. Potential difference,V1= 220v. Power,P1 = 100w. In case of Bulb 2. Potential Difffernce,D2 =220v. Power,P2 = 60w. Now, since they are connected in parallel combination hence they have same potential difffernce and the total Current in the circuit is given the sum of currents flowing in both the resistors. Power = Potential ...
WebJan 22, 2024 · The resistance of the bulb is defined as R =V 2 /P So the resistance of 50W bulb is double than the resistance of 100W bulb. When they are connected in series the current through both bulbs is same. Hence 50-watt bulb will be brighter because P=I 2 R. In parallel, the voltage will be same in both bulbs.
