Question:

In the question given below there are 2 statements marked as Assertion (A) and Reason (R). Choose the correct alternative from the following options.

Assertion (A)- With the help of photovoltaic cells, solar energy can be converted into electricity.

Reason (R)- These cells use special kind of materials to capture solar energy and then convert the energy into electricity.

Options:

Both (A) and (R) are true and (R) is the correct explanation.

Both (A) and (R) are true but (R) is not the correct explanation of (A).

 (A) Is true but (R) is false.           

(A) Is false but (R) is true.

Correct Answer:

Both (A) and (R) are true and (R) is the correct explanation.

Explanation:

The correct answer is Option 1: Both (A) and (R) are true and (R) is the correct explanation.

Explanation:

  • Assertion (A): With the help of photovoltaic cells, solar energy can be converted into electricity. This statement is true. Photovoltaic cells, also known as solar cells, are devices that convert sunlight into electricity. They are made up of semiconductor materials that absorb sunlight and generate an electrical current.
  • Reason (R): These cells use special kind of materials to capture solar energy and then convert the energy into electricity. This statement is true. Photovoltaic cells use special types of semiconductor materials, such as silicon, to capture sunlight and convert it into electricity. These materials have specific properties that allow them to absorb light energy and generate an electrical current.

Therefore, both the assertion and the reason are true, and the reason directly explains the assertion. Photovoltaic cells use specialized materials to capture solar energy and convert it into electricity, which is the basis for solar power technology.
