Answer : The correct option is, (B)
Explanation :
Electrical energy : It is defined as the movement of the electrons thought the wire.
Chemical energy : It is a type of energy which is stored in the bonds of a chemical compounds. During the chemical reaction, chemical energy is released in the form of heat.
Sound energy : It is a type of energy which is produced when an object vibrate.
Mechanical energy : It is a type of energy that can be used to do work.
The option A is incorrect because in this process, electrical energy being converted to the sound energy.
The option B is correct because in this process, electrical energy being converted to chemical energy. An oxidation-reduction reaction occurs in the storage battery.
The option C is incorrect because in this process, mechanical energy being converted to mechanical energy.
Hence, the option (B) A storage battery is charged using an electric current is an example of electrical energy being converted to chemical energy.
