Why Is Alternating Current (AC) Preferred for Power Grids and Household Appliances?

Definition:

Alternating Current is the flow of electric charge that periodically reverses direction. It’s like a wave, constantly changing direction. This type of current is what powers our homes and industries.

Applications:

  1. Power grids: AC is the standard for transmitting electricity over long distances due to its efficiency. It’s the backbone of our modern electrical infrastructure.
  2. Household appliances: From your refrigerator to your hairdryer, most home appliances run on AC power. This is because AC can handle the high power demands of these devices.

Advantages:

  1. Efficient for long-distance transmission: AC can travel long distances with less energy loss, making it ideal for power grids. This efficiency is due to the ability to transform AC voltage up or down as needed.
  2. Ability to transform voltage: AC can be easily transformed to different voltages, which is essential for adapting different applications and safety. This flexibility is a key advantage over DC in many situations.
