उत्तर

  1. When a bulb is connected to a battery, then the chemical energy of the battery is transferred into electrical energy.
  2. When the bulb receives this electrical energy, then it converts it into light and heat energy.
  3. Hence, the transformation of energy in the given situation can be shown as:

Chemical Energy → Electrical Energy → Light Energy + Heat Energy
