Two electric bulbs marked 25W-220V & 100W-220V are connected in series to 440V supply. Which of the bulbs will fuse? a) 100W b) 25W c) neither d) both.?

Question

Answer

Answer

These two electric bulbs are marked with their wattage and voltage, indicating that they are designed to operate at a power of 25 watts and a voltage of 220 volts. This information is important for choosing the appropriate power supply and ensuring that the bulbs are compatible with the electrical system. It is also important to note that the wattage of the bulb will determine its brightness, with higher wattage bulbs producing more light.
