Tf is this question doing on 10th class 💀💀💀

frfr and that too in cbse

[@TEAM-BRAHMA]

So basically it means that if a lamp is rated at some voltage lower than that of the battery , it will operate on that voltage and will give the remaining voltage to the end of circuit or somewhere else (like in this question, the lamp was 12V but the battery was of 15, so the lamp will operate on 12 only instead of 15.

@@TEAM-BRAHMA this is a really good question actually, thanks for asking! Let me clarify: In this question the lamp was operating at a different voltage because of the resistors. Otherwise the lamp or any other device will always operate at the voltage of the battery (if there are no other resistors or components).

Bro this question is in our class 10 sample question paper which is provided by cbse(central board of secondary education) itself (in india)

[@ein_gang]

Indian syllabus is more advanced, I agree. But this question is taken from past paper question bank of AS physics.

[@BajarangiGaming7]

Which book book is question

[@ein_gang]

@BajarangiGaming7 this question is taken from past papers of Edexcel A-levels physics exams.

[@BajarangiGaming7]

Which class

[@ein_gang]

We are following Edexcel A-Levels 1st year syllabus (equivalent to 11th grade). This curriculum is mostly taught in the UK.
