In this paper, we study the Penrose process and the maximum energy extracted from the collision of two particles near the Kerr–Newman black hole with WGC condition. We show that these conditions increase the energy extracted from the black hole. In this process, two particles collide in the ergosphere region, leading to two more scattered particles. The fate of these particles leads to falling into a black hole or escaping to infinity. The WGC condition leads to an increase in the energy of the particles escaping to infinity. We also investigated the amount of energy extracted by particles with different spins from the black hole. These achievements will help identify and study other black holes and spinning particles in astrophysics and make how black holes work more transparent in WGC conditions.
