A battery lights a bulb. Describe the energy changes involved in the process.


Answer :

When a bulb is connected to a battery, then the energy of the battery is transferred into voltage. Once the bulb receives this voltage, then it converts it into light-weight and warmth energy. Hence, the transformation of energy within the given situation may be shown as:

\( Chemical \ Energy \ \to \ Electrical \ Energy \ \to \ Light \ Energy \ \to \ Heat \ Energy \) .
