What are the primary arteries for power to reach metropolitan areas from a generating station?

• A. Distribution panels
• B. Circuit breakers
• C. Transmission lines and substations
• D. Power plants

Answer: (C)

The primary arteries for power to reach metropolitan areas from a generating station are transmission lines and substations. Transmission lines carry high-voltage electricity over long distances from power plants to substations, which then step down the voltage for distribution. This system is essential because it allows for efficient energy transfer across large areas, minimizing energy loss during transmission. Substations play a crucial role in regulating and distributing the power to various distribution networks that service urban and metropolitan areas. In contrast, distribution panels and circuit breakers serve different functions within the electrical system. Distribution panels manage the distribution of electricity within buildings or localized areas but do not serve the purpose of transporting power over long distances. Circuit breakers are safety devices designed to protect electrical circuits from overloads and short circuits; they do not function as conduits for power transmission. Power plants are the sources of electricity generation but are not the means by which electricity is delivered to consumers. Therefore, transmission lines and substations are the critical components that connect generation with urban demand, ensuring that power effectively reaches metropolitan areas.
