All Advantages listed here :
More Power
1.Probably the biggest advantage of AC over DC is that you can generate much more power from AC than DC. Alternating current is generated by large turbines. Direct current normally comes from batteries or sometimes from solar panels. Solar panels large enough to power entire cities would take huge amounts of land. Batteries use chemical reactions to produce electricity. Producing a huge battery would be expensive and impractical. Large turbines can be easily built and powered using steam, nuclear or hydraulic power.
Long Distance Transmission
2.The ability to generate higher voltages with AC translates into the ability to transmit that power over longer distances. Alternating current is generated at power stations and transmitted through power lines to substations that can boost AC and keep it going farther distances.
Conversion
3.In some operations, direct current may be preferred. However, it is easy to convert AC to DC by using simple ...more
