Welcome to Electrical and Computer Engineering!

'Electrical science has revealed to us the true nature of light, has provided us with innumerable appliances and instruments of precision, and has thereby vastly added to the exactness of our knowledge.' -Nikola Tesla (Electrical Review, January 27, 1897 http://www.tfcbooks.com/tesla/1897-01-27.htm (Links to an external site.))

<< This picture is a simulation of how the electrical fields (and currents) would flow from a charge on the left to a charge on the right through the 'U'. By Dr. James Nagel, PhD UofU
