If two bulbs of wattages 25 and 100 respectively, each rated 220V are connected in series with the supply of 440V, which bulb will blow up first?

If two bulbs of wattages 25 and 100 respectively, each rated 220V are connected in series with the supply of 440V, which bulb will blow up first?

Answer:

In a series circuit, the total voltage is divided among the components based on their resistances (or wattages in this case, assuming a constant resistance for simplicity).

Given two bulbs rated at 25W and 100W respectively, both rated at 220V, and connected in series to a supply of 440V, the bulbs will not operate properly.

The 25W bulb, designed for 220V, might be able to handle the voltage overload momentarily due to its lower wattage, but it will likely blow up or burn out quickly due to the excessive voltage (440V).

The 100W bulb, also designed for 220V, would likely blow up even faster as it is exposed to twice its rated voltage.

However, it’s important to note that connecting bulbs designed for a specific voltage (220V in this case) to a much higher voltage (440V) can be extremely dangerous and can cause damage to the bulbs, as well as potentially causing fire hazards or other safety risks.
