Dear Yashraj
 
Transformation of Energy:
  • Energy can be changed from one form to another.
  • The change of energy from one form to another is called as the transformation or conversion of energy.

     Examples:

  1. The electrical energy in an electric bulb is converted into heat and light energy.
  2. The electrical energy in an electromagnet is converted into magnetic energy.
  3. A cell or a battery converts chemical energy into electrical energy.
