(b) The lamps are designedto "fail-short". If a filament fails, the lamp shorts so that it has no resistance. The other lamps continue to light and the current increases. The lamps are connected through a fuse that blows when the current rises above 0.9 A. At this current, the resistanceof eachlamp is 5% greaterthan its normal working resistance. Calculate the maximum number of lamps that can fail before the fuse blows
