Abstract
Bu çalışmada, sonlu bir devirli grubun power grafının komşuluk matrisi yapısı dikkate alınarak, sonlu devirli grupların power graflarının enerjileri için bazı alt ve üst sınırlar elde edilmiştir. Daha sonra devirli bir grubun mertebesinin bir asal sayının pozitif tam sayı kuvveti olması durumu ile bu devirli gruba karşılık gelen power grafın tamlığı arasındaki ilişki kullanılarak bazı sonuçlar verilmiştir.

Abstract
In this study, some lower and upper bounds were obtained for the energies of the power graphs of finite cyclic groups by considering the adjacency matrix structure of the power graph of a finite cyclic group. Then, some results are given using the relationship between the case where the order of a cyclic group is the positive integer power of a prime number and the completeness of the power graph corresponding to this cyclic group.
