A house uses AC (Alternating Current). This is because AC is more efficient for transporting electricity over long distances and can easily be converted to different voltages with transformers, making it ideal for residential use. Most household appliances and lighting are designed to operate on AC power.

FAQs & Answers

  1. Why is AC preferred over DC for home electricity? AC is preferred because it can be transmitted efficiently over long distances and easily transformed to different voltages, making it suitable for residential use.
  2. Can household appliances run on DC power? Most household appliances are designed for AC power, though some electronics internally convert AC to DC to function properly.
  3. What role do transformers play in household electricity? Transformers adjust the voltage of AC electricity to safe levels for residential use, enabling efficient power delivery.
