Which of the following is NOT a renewable energy source?

  1. Solar energy

  2. Wind energy

  3. Hydropower

  4. Fossil fuels


Correct Option: D
Explanation:

Fossil fuels, such as coal, oil, and natural gas, are non-renewable energy sources because they are formed from the remains of ancient plants and animals over millions of years and cannot be replenished at a rate comparable to their consumption.

What is the primary function of a solar cell?

  1. To convert sunlight into electrical energy

  2. To store electrical energy

  3. To generate heat

  4. To produce hydrogen fuel


Correct Option: A
Explanation:

Solar cells, also known as photovoltaic cells, are designed to absorb sunlight and convert it directly into electrical energy through a process called the photovoltaic effect.

Which of the following is a type of energy storage technology?

  1. Batteries

  2. Fuel cells

  3. Supercapacitors

  4. All of the above


Correct Option: D
Explanation:

Batteries, fuel cells, and supercapacitors are all examples of energy storage technologies that can store electrical energy and release it when needed.

What is the main component of a wind turbine?

  1. Blades

  2. Generator

  3. Tower

  4. All of the above


Correct Option: D
Explanation:

Wind turbines consist of blades that capture the wind's kinetic energy, a generator that converts this energy into electrical energy, and a tower that supports the entire structure.

Which of the following is a type of fossil fuel?

  1. Coal

  2. Natural gas

  3. Oil

  4. All of the above


Correct Option: D
Explanation:

Coal, natural gas, and oil are all types of fossil fuels, which are formed from the remains of ancient plants and animals over millions of years.

What is the primary function of a hydroelectric dam?

  1. To generate electricity

  2. To control flooding

  3. To provide irrigation

  4. All of the above


Correct Option: D
Explanation:

Hydroelectric dams serve multiple purposes, including generating electricity from the flow of water, controlling flooding by regulating water levels, and providing irrigation for agricultural purposes.

Which of the following is a type of renewable energy source that utilizes heat from the Earth's interior?

  1. Geothermal energy

  2. Solar energy

  3. Wind energy

  4. Hydropower


Correct Option: A
Explanation:

Geothermal energy is a renewable energy source that harnesses heat from the Earth's interior, typically from hot rocks or underground reservoirs of hot water or steam.

What is the main component of a nuclear reactor?

  1. Fuel rods

  2. Control rods

  3. Reactor core

  4. All of the above


Correct Option: D
Explanation:

Nuclear reactors consist of fuel rods containing fissile material, control rods to regulate the nuclear reaction, and a reactor core where the nuclear fission process takes place.

Which of the following is a type of energy-efficient lighting technology?

  1. Incandescent bulbs

  2. Compact fluorescent lamps (CFLs)

  3. Light-emitting diodes (LEDs)

  4. Halogen bulbs


Correct Option: C
Explanation:

Light-emitting diodes (LEDs) are a type of energy-efficient lighting technology that consumes less energy and lasts longer compared to traditional incandescent bulbs.

What is the primary function of a transformer in an electrical grid?

  1. To increase or decrease voltage

  2. To convert AC to DC or vice versa

  3. To regulate the flow of electricity

  4. To protect against electrical faults


Correct Option: A
Explanation:

Transformers are used in electrical grids to increase or decrease voltage levels, allowing for efficient transmission and distribution of electricity over long distances.
