The output should be equal, but it wasn't hence you had to find the powerloss.it said the input voltage was 12v and the input current was 0.05A,
the output voltage was 6v when the output current was 0.2mA.
shouldnt the output I > Input I since its a step-down transformer???
Didn't it ask for the power loss?youngguz said:Did any1 think the data in the transformer question was wrong.

Lol yeah i know, that transformer lost a shitload of power!!youngguz said:Did any1 think the data in the transformer question was wrong.

Yeah, i think i got something like that.edcox said:Yeah i got that 0.5998 thingo..
Anyone else think that motor was frikkin huge or did i get that wrong. i said like 278 or something for the torque.
Also that question about thought and reality was a little philosophical don't you think?
Well, its a dot point, so I don't see anything wrong with them asking itedcox said:Also that question about thought and reality was a little philosophical don't you think?
From my vauge recollection of the questions:shais said:Can someone answer the superconductor Question ???
0.5998 ronded off to 1 ? because 300nm is no decimalsBackCountrySnow said:Yeah, i think i got something like that.
I thought it was wrong because it's a stupidly high number.
...wrong questionandrewmurphy said:0.5998 ronded off to 1 ? because 300nm is no decimals
Oh god. Was that torque question .40 cm or 40 cm? Was the 278 you got for the Torque or the force on the long wire?Cob-was-here said:Well, its a new personal best for me. Only 2 questions unanswered because I didn't have enough time (2 of the black body ones. I left them until last. Bad choice). Our exam was only on core topics with the options part consisting of more core questions. We seriously haven't started our option yet!!! (I'm nearly finished human story for Bio)
Anyway, yes, i got 0.5988 power loss and got around 278 or whatever for the torque question. As for that Einstein question. Well. Uh. I talked absolute shit, but i think it translates mostly to what DunnyBasher said. Something about classical physics being different to relative physics or somethin. I'm just disappointed that i didnt get to talk much about Tesla. I know soooo much about him.
I worked until the time was out. I'm not sure if thats a good or bad thing. I looked around at all the other people and they had finished like an hour before the end. How did everybody else go time-wise?
Basically, I could've gone better if i didnt have tonsellitis.
the transformer question answer was 0.5998w power loss was this rounded up to 1 as 300nm had no decimals.. i never undertand sig figuresCob-was-here said:...wrong question
Lol...funny thing...I put all the values straight into my calculator to determine force and got around...4000 odd...which multiplied by 0.08 gave me a torque of ~300..I thought it was too high, so I went and tried using a different method...finding the force in an individual wire and multiplying by the number of coils...didn't work out too well, so went back to the original method and got a force of ~54000N...which I knew was different, but because I had written up the working assumed it was correct...probably put the incorrect units in somewhereCob-was-here said:278 or whatever for the torque question.
That's what I got. We done this paper yesterday (Monday), although it had no CSSA cover sheet, but same questions.dolbinau said:There for, there was 0.5988 Watts of power loss.
