Аннотация:Solutions of the Klein-Gordon equation are used to obtain the absorption cross section and spectral densities of the number of particles and the Hawking radiation power of a macroscopic charged black hole. The discharge law and the rate of the surface area of the horizon (the entropy) due to pair production are studied.In the case of strongly charged holes our approach gives results which are equivalent to those obtained in the approximation of a constant,uniform electric field.
