Most homes rely on alternating current (AC) for their electricity, and it’s easy to see why. AC offers some major benefits when it comes to transmitting and distributing power efficiently. Let’s dive into a few key reasons that make AC the go-to choice for our everyday electricity needs.
Easy transmission and voltage conversion:
Alternating current is easily transmitted over long distances by means of transformers that raise or lower the voltage as it changes levels. High-voltage alternating current means that less energy is lost when it is transmitted over long distances, and when it reaches our homes, the transformer reduces it to a safe level for use.
Transmission Distance:
Alternating current outperforms AC in terms of long distance transmission. This is so that voltage drops caused by resistance over long distances can be compensated for by using transformers.
Power generation and cost:
Due to the use of rotating generators, the production of AC power is relatively simple and cost-effective. This simplicity helps in making the production and distribution of electricity affordable for everyone.
Wide applicability:
Most of our household appliances, such as televisions, refrigerators, and washing machines, are designed to use alternating current. Their circuitry can handle AC power seamlessly, although it may need to be converted to DC power for use in specific components.
Safety:
While high-voltage AC can be dangerous, its high-frequency nature means it’s relatively safe at lower voltages, which is what we typically use in our homes.
It’s worth noting that more devices in modern homes – such as cell phone chargers, computers, and routers – use DC power internally. These devices typically use an adapter to convert the AC power in the outlet to DC power. DC power has its advantages, such as energy efficiency, distance stability, and better control in applications such as electronics and electric vehicles. However, while both AC and DC power have their advantages, AC power is the backbone of home electricity, ensuring that the power we use every day is always available and safe.
