Types of Energy
• Heat
• Electromagnetic
• Nuclear
• Mechanical
• Chemical
Energy Transformation
• Energy can neither be created nor destroyed. We can change only its formsby appropriate energy- conversion process.
• Energy conversion process takes place between well known pairs
• Electrical↔Mechanical, Electrical↔ Chemical, Electrical↔ Thermal, Electrical↔Sound
Electrical↔ Optical
Transforming (to and from) Electromagnetic energy
• Basic Idea: Electromagnetic Induction
• Time changing magnetic field induces electric field.
