Question

When it is plugged into a wall outlet, the alarm clock lights up with a time display. What kind of energy transformation takes place?

Answer 1

The  energy change taking  place in the  clock is the electrical energy to the  mechanical  energy to the light energy.

Explanation:

• The alarm clock will work in the battery in the form of electrical energy. Then due to the current passed the electric motor rotates the blade.
• Then the energy is converted into mechanical energy.
• Then the mechanical energy generates the light and When it is plugged into a wall outlet, the alarm clock lights up with a time display.
• This is the energy transformation taking place in the alarm clock.
