LEARNING OUTCOMES
After studying Electrical & Electronics Engineering Materials (EEEM) subject, students will able to:
• Identify electrical and electronics engineering materials/component
• Select proper conducting material for a particular application
• Select a proper insulating material for a particular application
• Suggest an alternate material if proper material is not available
• Procure various electrical and electronics engineering material available in the market
• Select proper magnetic material for a particular application
• Make use of engineering material used for fabrication of particular electrical machine
• Select gaseous material for particular application
INSTRUCTIONAL STRATEGY
The teacher should bring different materials, electronic components and devices in the class while taking lectures and explain and make students familiar with them. Also he may give emphasis on practical applications of these devices and components in the field. In addition, the students should be given exercises on identification of materials used in various electronic gadgets etc .and be encouraged to do practical work independently and confidently.
MEANS OF ASSESSMENT
− Assignments and quiz/class tests, mid-term and end-term written tests, model/prototype making.
− Actual laboratory and practical work, model/prototype making, assembly and disassembly exercises and viva-voce.
