So Im at the point in my electrical engineering degree where I get to choose electives, but because I feel like I'm not fully familiar with the classes I can choose from.. I've got a few questions: 1. what is radio systems about? Google tells me its about FM/AM radio broadcasts 2. do any electrical engineers work in building services? Would you be able to tell me more about what you do? And what areas of electrical engineering is required for this field? 3. What is power systems about? Is there a reason why a course on transmission lines is not included in power systems? (isn't power systems about power grids and transporting the power to households?) thanks for your time!!
