b

the current starts to flow... and it goes through resistor to lamp.. but not from switch as its not complete so current to tht way is wasted... but wen switch is closed.. the current tht is wasted up going there adds too.. so now it becoomes more current.. so more current = more brightness. Hope u understand ?

i thik its A too..

the steam would cause a little expansion but this particular shape would prevent it..

pressure changes are not in the lime light as steam has to do more about expansion

n a parallel circuit the voltages across the devices are same but the current is diffferent

therfore --> I (1) + I (2) = I

when lamp N is removed there is no I (2)
soo I has to be less

it is C

dude i asked an electrical engineer right now and he said it should be A because the ammeter reads the total current and if one removed the total current supplied by the battery would still be the same it is so obvious they are wrong  :-\ >:(
