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 the current at point R, I=100KW/22000V. I don't get why they used 22000V. Shouldn't they deduct the voltage loss from that value? here's their answer!
