How the Electricity Grid Works
As electricity flows through the wires, some of it dissipates as heat through a process called resistance. The higher the voltage is on a transmission line, the less electricity it loses. (Most of the electric current flows close to the surface of the transmission line; using thicker wires would have minimal impact on transmission losses.)
Why use line transects?
Line transects are used when you wish to illustrate a particular gradient or linear pattern along which communities of plants and, or animals change. They provide a good way of being able to clearly visualise the changes taking place along the line.
