Why AC is Superior to DC for Power Transmission: Key Benefits Explained

Discover why AC is more efficient than DC for power transmission over long distances. Learn about safety and cost advantages.

21 views

AC (Alternating Current) is favored over DC (Direct Current) for power transmission because it is more efficient for long distances. AC voltage can be easily transformed to higher or lower levels, reducing energy loss over power lines. Additionally, AC systems are generally safer and less expensive to maintain, making them optimal for residential and commercial power solutions.

FAQs & Answers

  1. What are the advantages of AC over DC? AC is more efficient for long-distance power transmission, easy to transform voltage levels, and generally safer and cheaper to maintain compared to DC.
  2. Why is AC used for residential power? AC is preferred for residential power systems because it can be easily stepped up or down in voltage, reducing energy loss and making it safer for household use.
  3. Can DC be used instead of AC for power transmission? While DC can be used, it is typically less efficient for long distances due to higher energy loss. AC is generally favored for most transmission applications.
  4. What are some applications of AC power? AC power is commonly used in residential homes, commercial buildings, and industrial settings for lighting, heating, and powering appliances.
