hello dear friends ^-^


option (c) is correct..


Dear Student

When the bulbs are connected in parallel, each bulb has V across it, each draws 100/V A, and each dissipates 100 watts. Both bulbs glow at their full brightness. The total power dissipated across these two bulbs is two times 100, or 200 watts (or 2(100/V) A × V = 200 W).

hope its help uh!!!
