Hi Ziyad,
I think that the following materials will be useful for you:
1. You can find a list of files (PDF/Mathcad) on the PTC site (section "Electrical Engineering") available on the page "Mathematical Engineering Resources":

http://www.ptc.com/appserver/search/mathcad.jsp
2. Video "Mathcad in Electrical Engineering" (duration 38 minutes): http://www.ptc.com/WCMS/files/42726/en/flash/index.htm
3. A review of the book "Mathcad for Electrical Engineers and Technologists": http://communities.ptc.com/docs/DOC-1591
P.S. In an attachment, you can find the e-book "Topics in Electrical Engineering" for Mathcad and some articles dedicated to teaching of electrical engineering with Mathcad.
