Two electric bulbs marked 25W -220V And 100W - 220 are connected in series with 440 V supply. Which of the bulb will fuse??
Hii Nisha,
The answer for this will be the bulb marked with 25W because it is having higher resistance. The rated power of 25W is less than 100W, this means that it has higher resistance since rated power is marked at same voltage supply. Since they are in series,therefore, the current passing through them will be same as a result 25W will have higher resistance.
Hope this helps.
