An AC power source is most commonly utilized in providing a reliable and constant output current that is completely independent of the input and load power line with variations. The use of such an option can include generating magnetic fields, testing circuit breakers and other products, and much more. For this reason, an AC power source is something you could seriously benefit from, no matter the application.
An AC power source can have the voltage changed easily with the use of a transformer. During use, high voltage should suffer fewer losses in long transmission lines, which can make it possible for voltage to be reduced and then safely used inside a residential or commercial property. An alternative to this option is to use coal burning generators every few blocks within a city, which is a decidedly old-school approach that quickly became overshadowed by such great inventors as Tesla.
The biggest advantage of an AC power source over DC can be found in power transmission, with the former being far more efficient. Hydroelectric power was an early favorite in regard to the former type, and AC simply performs better over long distances than any DC alternative. Both AC and DC experience power loss in long lines due to resistance within the wires, but a higher voltage results in a lower current, which in turn reduces losses.
When using transformers, it is a simple task to boost AC voltage to the high levels needed to avoid excessive power loss while reversing the process at the consumer end. DV voltage will not work with a transformer, making AC the best option for the future. No matter the type of use you get out of your AC source, you are sure to enjoy the many great results of this cost-effective and highly useful option.
