Technology And Livelihood Education (T.L.E-II) - Quiz

This questioner is intended for 2nd year student at MCS.


Questions and Answers
  • 1. 

    He called the “Father of Electricity.”

    • A.

      Edison

    • B.

      Gilbert

    • C.

      Faraday

    • D.

      Thales

    Correct Answer
    B. Gilbert
    Explanation
    Gilbert is referred to as the "Father of Electricity" because he was the first person to systematically study electricity and magnetism. He conducted extensive experiments and observations, laying the foundation for the understanding of electrical phenomena. His work on magnetism and static electricity was groundbreaking and paved the way for future scientists like Faraday and Edison to further advance the field of electricity. While Faraday and Edison made significant contributions to the development of electricity, Gilbert's pioneering work earned him the title of the "Father of Electricity."

    He discovered electricity.

    • A.

      Edison

    • B.

      Gilbert

    • C.

      Faraday

    • D.

      Thales

    Correct Answer
    D. Thales
    Explanation
    Thales is the correct answer because he is credited with discovering electricity. Thales was an ancient Greek philosopher and scientist who lived around 600 BC. He is known for his investigations into the natural world and is considered one of the first philosophers of science. Thales observed that rubbing amber could attract small objects, which is an early form of static electricity. This discovery laid the foundation for the understanding and study of electricity in the future.

    Rate this question:

  • 3. 

    Materials that allow passage of electrical current are

    • A.

      Conductors

    • B.

      Tapes

    • C.

      Insulators

    • D.

      Sockets

    Correct Answer
    A. Conductors
    Explanation
    Conductors are materials that allow the passage of electrical current. They have low resistance and can easily conduct electricity. Examples of conductors include metals like copper and aluminum. In contrast, insulators are materials that do not allow the passage of electrical current and have high resistance. Tapes and sockets are not specific materials but can be made from either conductive or insulating materials. Therefore, the correct answer is conductors.

  • 4. 

    It is considered the best conductor of electricity

    • A.

      Aluminum

    • B.

      Copper

    • C.

      Brass

    • D.

      Silver

    Correct Answer
    A. Aluminum
    Explanation
    Aluminum is considered the best conductor of electricity because it has a high electrical conductivity. It is able to efficiently transmit electric current due to its abundance of free electrons, which are easily able to move through its atomic structure. This property makes aluminum a popular choice for electrical wiring and transmission lines.

    Rate this question:

  • 5. 

    This material is mostly used in the manufacture of transmission lines.

    • A.

      Aluminum

    • B.

      Copper

    • C.

      Brass

    • D.

      Silver

    Correct Answer
    A. Aluminum
    Explanation
    Aluminum is the correct answer because it is widely used in the manufacture of transmission lines. Aluminum has excellent conductivity and is lightweight, making it an ideal material for transmitting electricity efficiently over long distances. Additionally, aluminum is more cost-effective compared to other metals like copper, brass, and silver, which further contributes to its popularity in transmission line production.
