Question

Which of the following transform solar energy into electricity

• A. Wind energy
• B. Solar cell
• C. Solar cooker
• D. Biogas plant

Answer 1

The correct option is B

Solar cell

Explanation for correct options

Solar energy is converted into electricity by using a device made up of silicon called a solar cell. These devices are mostly mounted on inclined rooftops to increase the amount of incident radiation.

Explanation for incorrect options

1. Wind energy - It is a source of energy used to generate electricity by using windmills
2. Solar cooker - It is a device used to prepare food from the heat energy received from the sun.
3. Biogas plant - It acts as a facility for the production of biofuel by providing an anaerobic condition for the production of methane gas via the fermentation process

Thus, solar energy is converted into electricity by using solar cells.

Hence, the correct option is (B).
