    Question

    Electrical energy is changed to ____ in buzzer.

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

    Hint:

    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.
