Which of the following is an example of electrical energy being converted to chemical energy?
a. a loudspeaker, which is plugged in to the wall, begins to project sound.
b. a storage battery is charged using an electric current.
c. the wheels on a machine begin to turn and move a conveyer belt.

Option (B) is the correct answer.

Explanation:

Electric energy is defined as the energy generated due to the movement of electrons through a wire or solution.

Whereas chemical energy is the energy present within the bonds of a chemical compound. When a chemical reaction takes place then if chemical energy is released then it will be in the form of heat.

So, when a storage battery is charged using an electric current then it means electric energy is being converted into chemical energy.

And, when a loudspeaker, which is plugged in to the wall, begins to project sound then electrical energy is being converted into sound energy.

Whereas when the wheels on a machine begin to turn and move a conveyer belt then work is being done. This means that electric energy is being converted into mechanical energy.

Thus, we can conclude that a storage battery is charged using an electric current is an example of electrical energy being converted to chemical energy.
