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:
- 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.
- 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:
- 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.
- 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.
