Question

Solar panels are used for harnessing solar energy. This solar energy is then used to rotate a fan. What are the energy changes which takes place?

• A. Solar energy $\to$ Electrical energy $\to$ Kinetic energy
• B. Kinetic energy $\to$ Solar energy $\to$ Chemical energy
• C. Solar energy $\to$ Chemical energy $\to$ Potential energy
• D. Solar energy $\to$ Electrical energy $\to$ Potential energy

Answer 1

The correct option is A Solar energy $\to$ Electrical energy $\to$ Kinetic energy

Solar energy is converted into electrical energy with the help of solar panels. This electrical energy comes to our houses and is used to run different appliances. One of them is rotating a fan. It can be said that the energy has been finally converted to kinetic energy. Energy transformation is Solar energy $\to$ Electrical energy $\to$ Kinetic energy
