Two electric bulbs rated 25w 220v and 100w 220v
Asked by admin @ in Physics viewed by 290 People
Two Electric bulbs marked 25w -220v and 100w -220v are connected in series to a 440v supply . which of the bulbs will fuse ?
Answered by admin @
Answer:
25w will get fused
Explanation:
As the rated power of 25w is less than 100w , it implies that 25w bulb has higher resistance . As in series connection , current through both the bulbs is same but heating in 25w bulb is more than that of 100w bulb .so ,25 w bulb will get fused
