What practical problems arise if household lighting bulbs are connected in series instead of parallel?
گھریلو روشنی کے بلب متوازی کے بجائے سلسلہ وار لگانے سے کون سے عملی مسائل پیدا ہوں گے؟
Solution & explanation
Supply voltage is shared, so rated bulbs may be dim. Switching off or failure of one can break the whole path, and independent control is lost. Parallel branches receive the same supply voltage and can operate independently.
