abstract:A charged black hole is a black hole that possesses electric charge. Since the electromagnetic repulsion in compressing an electrically charged mass is dramatically greater than the gravitational attraction (by about 40 orders of magnitude), it is not expected that black holes with a significant electric charge will be formed in nature.
We drew the conclusion that the frequency distribution of the non-thermal radiation from a general spherically-symmetric and chargedevaporatingblack hole depended on the time.
