So, I picked up this book and am working through it by myself. I am a bit stuck on problem 1.6:
In the bottom you can see how I'm approaching this. I'm assuming the transmission cable goes across NY, and New Yorkers draw power from different points along the line. Since they each draw power at 115V, then the total voltage at the station,
V@Station minimum, is 115 x 107V.
The power dissipated through one foot of cable is
(V@Station ^ 2) / Resistance per foot of cable
This worked out to be 2.645 x 1025W. And 1010W would be dissipated in 3.78 x 10-16 feet.
I haven't calculated the temperature because I don't know how to.
The last part of the question comments on these strange results and asks for a resolution to this problem. I'm guessing that, since power rises non linearly with voltage, we reduce the V@Station by the use of transformers in order to reduce power dissipation through the transmission cable.
Is this approach and the answer correct? Please add your own thoughts and point me in the right direction if I'm wrong.
