lol... thanks so much for your help! ^^

mm.. yes.. i see. By using the quadratic formula, i achieved two answers - the desired 4.55A and 10995.5A. To eliminate the second answer, can you say that it is not possible for 10995.5A being larger than 400A (which is the current of the secondary coil of the step down transformer) since the...

okay, i see. thanks! it'll be a pain if the loss was significant.. :P

sammyS- the voltage loss due to the resistance in the wire (2 ohms) gneil- ah, i see.. the answer for the current after voltage loss deduction is 4.55A also. But in an exam how would you know for certain that you don't need to deduct the voltage loss first? would you have to write ' the voltage...

hello! I was going over some questions on the vcaa site and there was this question in the year 2006 physics exam two. It was question ten. Here's the question (page 7 question 10) http://www.vcaa.vic.edu.au/Documents/exams/physics/2006physics2-w.pdf The answer said that in order to find...
