This question was a careless mistake man. I got the answer right already but i went to change it. Why? Because i think too much, and in the end i came up with some theory and put the wrong answer in!!

This is the question that i spent the most time on and the one i hated most. The question ask to determine a new value for the frequency to make it a purely resistor circuit, however i forgot the formular for it so what did i do? I did the question by trial and error. The answer for it could be anything from 0-infinity and i happily go do trial and error. In the end i gave up when i was almost there and wrote in the answer 1780Hz. And you know what? The answer was 1779.4Hz!!! I was SO close to it man!!

So yup, there goes my 6 marks and i ended up decreasing my chances of being top in my cohort. Haiz=( I'm just going to one corner and cry about it.
