    Rate this question:

  • 22. 

    Electricity prices are normally higher during peak times.

    • A.

      Yes

    • B.

      No

    Correct Answer
    A. Yes
    Explanation
    Electricity prices are typically higher during peak times due to increased demand. During peak hours, such as evenings when people are at home and using more electricity, the demand for electricity is higher than during off-peak hours. To meet this increased demand, power companies may need to generate more electricity or purchase it from other sources, which can be more expensive. As a result, they pass on these higher costs to consumers in the form of higher electricity prices during peak times.

    Rate this question:

  • 23. 

    Electricity prices are normally low on weekends.

    • A.

      Yes

    • B.

      No

    Correct Answer
    A. Yes
    Explanation
    Electricity prices are normally low on weekends because there is typically a decrease in demand during this time. Many businesses and industries are closed, resulting in less energy consumption. Additionally, households tend to use less electricity on weekends as people are often away or engaged in leisure activities. This decrease in demand leads to a surplus of electricity supply, which in turn lowers prices. Therefore, it is reasonable to expect that electricity prices are indeed low on weekends.

    Rate this question:

    Correct Answer(s)
    A. SMS
    B. Email
    C. Phone call
    D. Smart Meters
    E. Website
    Explanation
    Price changes can be communicated using various approaches such as SMS, email, phone call, smart meters, and website. These methods allow businesses to effectively reach out to their customers and inform them about any changes in prices. SMS and email are convenient ways to send instant notifications to customers, while phone calls provide a more personal touch. Smart meters can be used to automatically update customers about price changes in real-time. Websites also serve as a platform to display updated prices and information to a wider audience.
