Fossil Fuels And Electricity Production - Quiz

  • 2. 

    The process of creating an electric current by adjusting a magnetic field is called _______________.

    Explanation
    Electromagnetic induction refers to the process of generating an electric current by changing the magnetic field strength or by moving a conductor through a magnetic field. This phenomenon was first discovered by Michael Faraday in the 19th century and is the fundamental principle behind the operation of generators and transformers. The changing magnetic field induces an electric field, which in turn causes the movement of electrons and the creation of an electric current.

    The main components needed in electricity production are relative spinning of a wire in a ____________________.

    Explanation
    In order to generate electricity, one of the main components required is the relative spinning of a wire in a magnetic field. This is because when a wire moves through a magnetic field, it induces an electric current in the wire due to electromagnetic induction. This current can then be used to power electrical devices. Therefore, the presence of a magnetic field is essential for the production of electricity.

    What is the total efficiency of the fossil fuel conversion from coal to electricity in terms of percentage?

    Explanation
    The total efficiency of the fossil fuel conversion from coal to electricity is 35%, 35 percent, or simply 35. This means that out of the total energy contained in the coal, only 35% is converted into electricity, while the remaining energy is lost as waste heat.

  • 5. 

    Of gasoline, wood, natural gas, and coal, it is the one that has the highest energy content per gram. 

    • Gasoline

    • Wood

    • Natural gas

    • Coal

    Correct Answer
    A. Natural gas
    Explanation
    Natural gas has the highest energy content per gram among gasoline, wood, natural gas, and coal. This is because natural gas is primarily composed of methane, which has a higher energy content compared to the other substances. When burned, natural gas releases a large amount of heat energy, making it a highly efficient fuel source.

    I plug my kindle touch into the wall to charge it. The type of current coming from the outlet is direct current, or DC.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The explanation for the answer being False is that the type of current coming from the outlet is alternating current, or AC, not direct current.
