There are many different types of power sources, and here some of the most common types that are mainly used in electronics. These can be classified into two main types , AC and DC. DC have its subtypes, DC voltage and DC current, same goes for AC. 

DC voltage can be supplied by using a battery or  by a power supply circuit; power supply circuit is also a variable type supply depending on its design construction.

AC on the other hand is be supplied by the “power sockets” that are readily available at homes, or a generator that generates power using fuel. There are also variable types of AC power but it still depends on its design construction.
