25\,\,W,\,\,220\,\,V

bulb and a

100\,\,W,\,\,220\,\,V

bulb are connected in parallel across a

440\,\,V

line

View answer and explanation

Correct option: C

Both bulbs will fuse

The correct answer is Both bulbs will fuse because the voltage across each bulb will be approximately 220V, which is double their rated voltage, causing them to overheat and fuse.
