  • 4. 

    Which organization sets the standard voltages and frequencies for AC power worldwide?

    • International Electrotechnical Commission (IEC).

    • Institute of Electrical and Electronics Engineers (IEEE).

    • World Health Organization (WHO).

    • United Nations (UN).

    Correct Answer
    A. International Electrotechnical Commission (IEC).
    Explanation
    The organization that sets the standard voltages and frequencies for AC power worldwide is the International Electrotechnical Commission (IEC). The IEC is a global organization that establishes international standards for electrical and electronic technologies. It works to ensure the uniformity and compatibility of electrical systems across different countries and regions, promoting safety and efficiency in the use of electrical devices and systems on a global scale.

    Rate this question:

  • 5. 

    What are harmonics in AC power?

    • Frequencies higher than the fundamental frequency.

    • Fluctuations in voltage magnitude.

    • Irregularities in the waveform.

    • Disturbances caused by lightning strikes.

    Correct Answer
    A. Frequencies higher than the fundamental frequency.
    Explanation
    Harmonics in AC power refer to frequencies that are integer multiples of the fundamental frequency. The fundamental frequency is the primary frequency at which an AC power system operates. Harmonics are additional frequencies that can be present in the waveform, and they occur at multiples of the fundamental frequency.

    Rate this question:

  • 6. 

    What is the most common standard voltage and frequency of AC power worldwide?

    • 240V at 50Hz.

    • 110V at 60Hz.

    • 220V at 60Hz.

    • 120V at 50Hz.

    Correct Answer
    A. 240V at 50Hz.
    Explanation
    The most common standard voltage and frequency of AC power worldwide is 240V at 50Hz.

    Rate this question:

  • 7. 

    What is the purpose of power distribution in AC systems?

    • To convert AC power to DC power for household use.

    • To regulate the frequency of AC power.

    • To ensure electricity is evenly supplied to consumers.

    • To generate harmonics and disturbances.

    Correct Answer
    A. To ensure electricity is evenly supplied to consumers.
    Explanation
    The purpose of power distribution in AC systems is to ensure electricity is evenly supplied to consumers. Power distribution involves the transmission of electrical energy from power plants to various locations, such as homes, businesses, and industries. The distribution system plays a crucial role in efficiently delivering electricity to end-users while maintaining voltage levels within acceptable limits.

    What is the standard voltage and frequency of AC power in the United States?

    • 240V at 50Hz.

    • 120V at 60Hz.

    • 220V at 60Hz.

    • 120V at 50Hz.

    Correct Answer
    A. 120V at 60Hz.
    Explanation
    In the United States, the standard voltage for residential and commercial electrical systems is 120 volts, and the frequency is 60 hertz. This means that the electrical outlets in homes and businesses typically provide power at 120 volts, and the alternating current (AC) oscillates at a frequency of 60 cycles per second (hertz). This configuration is commonly referred to as 120V/60Hz.

    Rate this question:

  • 9. 

    How is AC power generated?

    • By converting DC power using a rectifier.

    • By rotating a coil within a magnetic field.

    • By connecting batteries in parallel.

    • By utilizing solar panels.

    Correct Answer
    A. By rotating a coil within a magnetic field.
    Explanation
    AC (alternating current) power is generated by rotating a coil within a magnetic field. This process is known as electromagnetic induction and is a fundamental principle in the generation of AC electricity. In a typical AC generator, a coil of wire is rotated within a magnetic field.

    Rate this question:

  • 10. 

    Which of the following is NOT a type of alternative electricity generation?

    • Solar power.

    • Nuclear power.

    • Wind power.

    • Hydropower.

    Correct Answer
    A. Nuclear power.
    Explanation
    Nuclear power is not typically considered a type of alternative electricity generation. While it is a low-carbon energy source, it is often categorized separately from traditional fossil fuels and renewable alternatives. Nuclear power involves the use of controlled nuclear reactions to generate heat, which is then converted into electricity. It has unique characteristics and considerations, including concerns about safety, waste disposal, and the potential for nuclear proliferation.
