    Can somebody explain why bulbs 2 and 4 are the only 2 bulbs to come on if bulb 1 is removed..

    thanks in advance..
  2. By my understanding the answer is wrong only bulbs 3 + 4 should come on. Bulb 2 is in series with bulb 1 and should not come on when the switch is closed.
  3. thats precisely why i'm having trouble with it.. lol..
  4. Agreed :thumright:
  5. I'm with you on this one with 3 + 4.
    By removing bulb you are effectively open circuiting bulb 2.
  6. a thickie grubber agrees with all above - are you seeing a trend here

    The question asks how many bulbs will light up, the answer is b) 2

    Nothing wrong with the options as the correct answer is there, the explanations however are complete bollox as has been pointed out and even the thick grubber above agrees.
  8. Even a non electrially minded scablifter knows someone fooked up there!

    Tsk. Technology eh?

    Someone taking their Australian GCSE Physics exam scans a question, posts it on here and gets an answer whilst the exam is still in progress.

    There was me dripping about not being allowed to use a calulator in my 'O- Levels'.[​IMG]
  17. change provider as you're obviously getting seen off from a nasty private company. PS if you ever get stuck on one of these questions follow this advice.....swicth off at the wall and then switch on again I believe it's called a Ferranti reset.

  18. This reminds me of the story about a supposedly mathematically astute course at Collingrad who were taught Ohm's Law as 'I=V/R'. When 'V=IR' appeared in an exam, they complained that this hadn't been part of the syllabus.
