What will happen when a 40 watt‐220 volt lamp and 100 watt‐220 volt lamp are connected in series across 40 volt supply?
Text Solution
Verified by ExpertsThe correct answer is:
D
Bulb (I): Rated current 
Resistance 
Bulb (II) : Rated current 
Resistance 
When both are connected in series across 40 V supply
Total current through supply
This current is less than the rated current of each bulb. So neither bulb will fuse.
