However, the voltage drop across each lamp will be proportional to its wattage. In this case, the 100 W lamp will have a voltage drop of 100 V, while the 40 W lamp will have a voltage drop of 40 V. This means that the 100 W lamp will be under a higher current and voltage than the 40 W lamp. As a result, the 40 W lamp will overheat and fuse.<\/p>\n<p>Here is a more detailed explanation of each option:<\/p>\n<ul>\n<li>Option A: The 100 W lamp will glow brighter. This is not correct because the current through each lamp is the same. Therefore, the 40 W lamp will also glow brightly.<\/li>\n<li>Option B: The 40 W lamp will glow brighter. This is not correct because the 100 W lamp will be under a higher current and voltage than the 40 W lamp. As a result, the 100 W lamp will glow brighter.<\/li>\n<li>Option C: Both lamps will glow equally bright.
