Within the alarm clock seen here, energy is transformed. It is time to get up! The alarm clock goes off. What are the energy transformations taking place in your alarm clock?

Explanation:

Please see the attached image of the alarm

Options  for the given question

A) electrical --> heat  --> sound

B) electrical  --> light  --> sound

C) electrical  --> chemical  --> light

D) chemical  --> electrical  --> mechanical

Solution -

The alarm shown in this picture is a digital alarm in which the chemical cells are the major source for storing electrical energy. These chemical cells then provide stored electrical energy as chemical energy which is again converted into electrical energy and as the alarm rings, the electrical energy is converted into sound energy.  

Thus, the energy transformations taking place are as follows –  

electrical energy -- Chemical energy -- Sound energy.  

Hence, option C is correct

current flows in a wire
