Question : Statement 1: Solar energy is a renewable source of power that utilizes sunlight to generate electricity.
Statement 2: Photovoltaic cells in solar panels convert sunlight directly into electrical energy.
Option 1: Both statements are true.
Option 2: Statement 1 is true, and Statement 2 is false.
Option 3: Statement 1 is false, and Statement 2 is true.
Option 4: Both statements are false.
Correct Answer: Both statements are true.
Solution : The correct answer is (a) Both statements are true.
Statement 1 is true. Solar energy comes from the sun, which is an abundant and renewable source of power. Sunlight is captured using various technologies such as solar panels to convert it into usable electricity.
Statement 2 is also true. Photovoltaic cells, commonly known as solar cells, are used in solar panels to convert sunlight directly into electrical energy through the photovoltaic effect. When sunlight strikes the cells, it excites the electrons, generating an electric current.
Both statements align with the generally accepted understanding of solar energy and its conversion into electrical energy using photovoltaic cells.
Question : Statement 1: Renewable sources of energy are inexhaustible and can be replenished naturally.
Statement 2: Solar power, wind energy, and hydroelectric power are examples of renewable sources of energy.
Question : Statement 1: Hydropower is a renewable source of energy that harnesses the energy of flowing or falling water to generate electricity.
Statement 2: Dams and turbines are used to convert the potential and kinetic energy of water into electrical energy.
Question : Statement 1: Wind power is a clean and renewable source of energy that harnesses the power of wind to generate electricity.
Statement 2: Wind turbines convert the kinetic energy of the wind into electrical energy.
Question : Statement 1: Nuclear power is a non-renewable source of energy that involves the use of radioactive materials.
Statement 2: Nuclear power plants generate electricity through nuclear fission, which releases a significant amount of energy.
Question : Statement 1: Geothermal energy is a renewable source of energy derived from the heat of the Earth's interior.
Statement 2: Geothermal power plants convert geothermal heat into electricity through steam turbines.
