In a battery chemical energy is converted to electric energy.
- When a bulb is connected to a battery, the chemical energy of the battery is transferred into electrical energy.
- When the bulb receives this electrical energy, then it converts it into light and heat energy.
- At first, the energy transformation takes place in battery and then bulb.
- Hence, the transformation of energy in the given situation can be shown as: Chemical Energy → Electrical Energy→ Light Energy + Heat Energy.
