lol i thought the same about the spesh exam last yr, and i ended up actually dropping 10 marks. ==

Ahmad:

--- Quote from: "bilgia" ---electric power qn13..i heard that it might flicker...i wrote what itute did though...
"The globe will be off. The 12V battery supplies a constant
voltage to the input of the transformer. This results in a constant
magnetic field in the transformer core, which in turns results in a
constant magnetic flux in the secondary coil of the transformer."

--- End quote ---


I thought you didn't need the flicker part, just didn't sound like the concept they were trying to test here.  8)

Galelleo:
yeah you didnt need to say anything about pulsing DC creating a changing flux... only that batteries are DC, so no change in flux, so no induced current, so no power to globe.

bilgia:
phew no mark lost then!
hooray for physics

abcat:
the hydrogen/sun question was a joke.

the study design does not state a requirement to know the composition of the atmosphere of the earth.

i got the answer, but not doing chemistry (assuming that's the subject where you would learn this stuff) i thought it was a tad unfair.
