Answer:
An electric bulb converts electrical energy into light energy. Electrical energy causes the filament in the bulb to become white-hot and give out light. So, in an electric bulb, the electrical energy is first converted into heat energy and then to light energy. This energy transformation can be written as,
Electrical energy → Heat energy → Light
Electrical energy → Heat energy → Light
