yagna from DPS, Surat
Subject :NSO    Class : Class 8

Ans 1:

Kingshuk Gupta from RN Podar school, Mumbai
Class : Class 9

Ans 2:

Amol Athawale from WoodRidge High, aurangabad
Class : Class 7
answer should be b because X will also lit up

Ans 3:

Vishwanath Halkeri from sudarshan vidya mandir, Bangalore
Class : Class 8

Ans 4:

SaiKrishna from Chettinad Vidyashram, Chennai
Class : Class 3
Option D is correct because current prefers the path that offers less resistance. The bulb provides resistance whereas the switch when closed does not. Hence correct answer is D

Ans 5:

Yatharth Agrawal from Indira National school, Pune
Class : Class 8
It must be B.The current finds a more direct path to Y, Making it brighter.But the current still reaches X because there is still a path. SOF Says otherwise.

Ans 6:

Abhay Agarwal from St Francis School, Ghaziabad
Class : Class 9

Ans 12:

I too am confused as current will also flow through both the bulbs when circuit is closed. It will pass through the switch first and hence lighting up bulb Y.
