Physics is sort of an elementary science. In a very broadway, it puts forward the elementary facts and theories only. If it could be conceptually / mathematically proven, that also will be done by physics.<br><br>Engineering (weather electrical/ mechanical/ electonics...) is largely application oriented. It uses the concepts from the elementary sciences and mathematics, and puts them into practice.<br><br>To explain with a verybasic example, when physics talks about Electromagnets, it tells you just the idea. When Electrical Engineering takes it up, it uses the idea of Electomagnets to develop a DC motor.<br><br>Thus, in a way, physical science affects Electrical engineering directly, I would say.<br><br>Regards<br><br>Umn.
