If you are looking for the best power source, there will be several options that will be represented to you during your search. While there are advantages and disadvantages to everything, the most highly recommended option is an AC power source. There are many reasons why this is so.
When it comes to generating electricity at the best price point, you really cannot beat power derived from alternating current. It is significantly cheaper than the other main popular option, that being direct current.
The transformers that are required to generate alternating current power do not need much maintenance during their lifetime of service. They are quite robust and
generally are not in need of repair very often. They are also quite cheap to purchase outright, making them an excellent option for those who want reliable power but are still on a budget.
When a transformer is used as your main AC power source, you are privy to a very wide range of different voltages. This gives you plenty of options when it comes to fulfilling your energy needs.
If you need to reduce the current at all, you can definitely do so using what is known as an inductor. This gives you the ability to completely control the current without any noticeable depreciation in actual power being generated.
If there is a time that comes when you need direct current instead of alternating current power, you can actually convert it by using a rectifier. This is easily done and lets you have access to both forms of mainstream energy delivery.
