  1. Heat energy
  2. Light energy
  3. Sound energy
  4. Chemical energy

hintHint:

The buzzer converts electrical energy into sound energy. 

The correct answer is: Sound energy


    Electrical energy is changed to sound energy in buzzer.
    • The electrical energy generated in a circuit is converted into some other forms of energy.
    • The energy forms depend on the electric load.
    • When current passes through a buzzer, electrical energy changes into sound energy.
