In this article, first we introduce six types of power graphs related to a graph (or directed graph), with the help of set theory.
Then we show that these newly defined power graphs are pairwise distinct by a few examples. Finally, we discuss the relation between Eulerian being the base graph and these six power graph types. Moreover, we express the relation between pairwise Eulerian of these power graphs.
