List of top Physics Questions on Resistance asked in AIEEE

Two electric bulbs marked $25W - 220V$ and $100W - 220\, V$ are connected in series to a $440\, V$ supply. Which of the bulbs will fuse ?

A material B? has twice the specific resistance of ?A?. A circular wire made of B? has twice the diameter of a wire made of ?A?. Then for the two wires to have the same resistance, the ratio $l_{B} / l_{A} $ of their respective lengths must be :
